Identification of Salagramas

The following account is taken from Sri-tattva-nidhi, an encyclopedia work in Sanskrit compiled by the late Maharaja of Mysore, Krishnaraja-wodeyar III (1780-1865). This monumental work in nine sections (which are called ‘treasures’, ‘nidhis’) is profusely illustrated by miniature paintings, and deals with the iconographical lore, subjects like Agama, Jyotisha, Sangita, and games and pastimes. The work, not yet seen in print, is in the nature of a compilation from hundreds of ancient and medieval manuals and texts. In the Vaishnava-nidhi section of this work, is the account on salagrama-stones as anionic emblems (symbols) of Vishnu, which is reproduced below, with a running translation in English.

The authors of this work has preferred the expression (dental) ‘saligrama’, which is also the more popularly used form in South India as well as North India, to the more correct ‘salagrama (palatal). And the account of these sacred stones has been taken from Narasimha-purana (Brahma-Narada-samvada). It may be seen that the account given in Sri-tattva-nidhi is rather haphazard and ill-organized, as compared with, for instance, the Salagrama-pariksha of Anupa-simha, who was the Maharaja of Bikaner. The text of the relevant and corresponding portions of Salagrama-pariksha have been given in the Appendix. This text, in contrast, is well-organized in three distinct sections (1) murtis relating to the ten avataras; (2) murtis relating to the twenty four forms (chatur-vimsati murti); and (3) miscellaneous forms (prakirna). Although all these forms are dealt with in Sri-tattva-nidhi, the descriptions are confined to those given in Narasimha-purana, whereas Salagrama-pariksha provides information from other puranas also.

Not only the order of deity-specific salagramas given here is haphazard, but some of these forms are repeated during the course of narration more than once, with different descriptions. While the major part of the text is taken from Narasimha-purana it is likely that passages have also been incorporated. The text, however, is unsatisfactory, especially when compared with words like that of Anupa-simha. But the matter here represents the South Indian tradition with regard to the Salagrama-lore.

(Narada tells Brahma that he was enlightened by the letter on many topics, and requests him that he be pleased to tell him about the other Salagrama-stones; about their origin, characteristics like colour and field, the differentiation in respect of divine form, and their suitability for purposes of worship.)
(Brahma proceeds to tell Narada about the salagrama-stones: their origin, identification, colour, field and other details.)
There is in the country of Avanti, a sacred mountain around which is the site which is the source of all the salagrama-stones.
Merely to remind oneself of this sacred site is to get rid of all the sins that have accumulated in the past. It is here that the river Gandaki, which destroys all sins, flows. By a touch of the waters of this river, one obtains residence in the realm of Vishnu. At the foot of the mountain in this site is a great stream known as Chakra-tirtha. The source of that river is said to be Vishnu himself; and in that mountain-stream, the god who wields the discus dwells. He abides here along with his consorts Lakshmi and Bhu, and in every stone that occurs in this sacred site. In the bowels of the rocks free from wind and cold the salagrama-stones are formed, with all adorable characteristics. On auspicious moments, these sacred stones get formed by the grace of God. The formation of spiral marks, the chakras, in these stones is explained as follows:

After thousands of years, the animal called vajra-kita (the adamentine worm) was born in these stones; the animal was in fact the form which Vishnu himself assumed.
Having entered into the bowels of these stones, the animal, golden coloured, mighty and brilliant like a flash of lightning, making a sweet noise, carves out the marks of discus of numerous kinds and various other marks with ease in the stones. The animal, who is Vishnu himself, the lord of Lakshmi, resides inside these stones for countless years; the presence of Godhead is unbroken here.
By a mere look at these stones, all the sins that one had accumulated will at once get destroyed.
The variety of forms, colours and other characteristics of the salagrama-stones.
The sacred stones may be white, yellow, red, black, green, tawny or ash-coloured; they may contain stains, and they may be multi-coloured.
The colours might be excessive or faded; the colours may otherwise be difficult to determine. The stones occur thus in many colours and forms.
The salagrama-stone is described as the ‘field’ for the presence of Godhead. The differentiations in this regard are dependent on the colours. The Vasudeva-salagrama is white in hue; the Hiranya-garbha-salagrama is yellow; the Pradyumna-salagrama is red.  Vishnu-salagrama is black stone; Narayana-salagrama is greenish in colour; Narasimha-salagrama is red; and Vamana-salagrama is like the atasi flower in colour (flax, Linum usitatissimum)
The colours have their own effects and influences.

The ash-coloured salagrama stone is especially suitable for worship by ascetics. The stones which are stained bring decay and destruction, the multi-coloured stones are also unfit for worship, unless it be Ananta-salagrama.

Highly coloured stones cause misery; the faded colours destroy the lineage; the colours which are indistinct and uncertain make for death.
The tawny-coloured stone is consort-killer; the bluish-stone brings wealth; the black-stones cause nourishment and prosperity; and the red-stone brings in sovereignty.

Excessively red-stone, however, deals death; the fair-coloured stone (viz. White) bestows wealth; multi-coloured stone makes for prosperity, while the faded colours are not useful when worshipped.

There is some confusion here with regard to the expression ‘bahu-varna’.

White coloured stones facilitate the obtainment of emancipation, and the stone with indistinct and uncertain colours destroy everything.

The salagrama stones differ with regard to their circumference (parimana), which is measured in terms of the size of the aperture.

The wise one will tie round the middle of the salagrama-stone a thread; and if the aperture is located at the spot which marks one-eight of the thread’s length, then the stone is of superior variety; it may also be of the middling variety. However, the stone having an opening in the one-third part is to be rejected. (However, Brahmanda-purana has a different prescription: There are different effects in terms of locations of operators. If the aperture is downward, it is terrible; the aperture on top will be useful only in magical rites of driving away the enemy; The apertures being even are especially meritorious, while the aperture on the sides will take away fortune.
If the aperture is crooked, it causes disease; if long-mouthed it devours everything (viz. Makes one impoverished). One should carefully examine the stone before ascertaining the deity-specification.

The supreme spirit abides in other multi-chakra-stones also.

The especial benefits of worshipping these different varieties of salagramas are narrated as under:

The Hiranya-garbha-salagrama brings all good fortune to the worshipper; it is like worshipping a thousand Shiva-nabha salagramas. It assures worldly prosperity.
There are, however, some salagramas which are difficult to identify with specific deities.

There are many deities in a salagrama as the forms of Vishnu are (viz. Innumerable). It would be impossible to separately identify all the forms of deities in salagrama even in a million years.

Now then the forms of the salagramas that must be avoided (viz. Not worshipped) are given:

The salagrama-stones which have irregular angles, which are burst, burnt, stained, or warm to touch must be avoided, as also those without chakras, or those which have been embrocated (rubbed and frayed), or which have crooked apertures.

Likewise the stones with numerous chakras, crooked chakras and chakras at the bottom, must be avoided.

The stones with many arrow-like lines, or with chakras which cannot be deciphered at all; the stones which are shaped like unripe bread-fruit (Artocarpus integrifolia) or like the deep-brown vegetable (Caculus melanoleucus).

The stones which are fettered (clasped or joined) or obstructed, the stones which have a cruel, terrible and awesome aspect, and the stones which have crooked snouts must be avoided.

The stones which are broken or burst open, the stones which are burnt, and the stones which are triangular in shape must be avoided, as also those which have internally split, and damaged; and the stones which have many scratches and fissures must also be avoided.

The effects of worshipping the salagramas which are to be avoided, are given below:
Worshipping a broken, burnt or warm stone makes one become impoverished; by worshipping joined stones, tangled chakras or a triangular stone, one will witness the death of relatives.

By worshipping a stone which has suffered an internal bursting, the worshipper’s relatives or children will die. By the worship of stones with no markings at all, one loses his wealth. By worshipping a stone which has a ferocious aspect, one gets great sorrow, and his family will be destroyed.

The salagramas must, therefore, be carefully examined with regard to their worthiness for worship.

In the salagramas abide all the fourteen realms, and therefore when one gifts the salagramas to others, God will be pleased.
However, one must accept a salagrama which has already been worshipped, and one must gift the salagrama after worshipping it. Both the receiver and the donor will obtain merit. But one who sells or buys salagramas will only be sinning.

The place where Salagramas are kept and worshipped is pure by that very act.
There is no offence or transgression in keeping or worshipping the salagramas which are split, burst, broken or cut open.

Elsewhere also it is said, a salagrama is still auspicious and worthy of worship if it has a chakra (intact), even if the stone is split, burst or broken.

The different salagramas indicated for celibates, householders are mendicants:

The celibate and the mendicant may worship salagramas with multiple chakras, salagramas which are muddy coloured, rude and crooked, and which are shaped like a lion (lion’s mouth).

The mendicant should worship the salagrama stones which have fire in the navel. The householder should worship only the salagramas of pleasant aspect.

In a house, two lingas or two salagramas must not be worshipped, nor should two Dvaraka-silas or two sun-stones should not be worshipped.

Three emblems of Ganesha or Devi must not be worshipped, nor two conches. An icon that is damaged must not receive worship; likewise ten salagramas (Matsya-murti and so on) must not be worshipped.

In a house, the salagramas that are burnt or damaged in fire must not be worshipped, for otherwise great anxiety will be occasioned.

An even number of salagramas must be worshipped, except when they are only two (in which case, they must not be worshipped); and an odd number of salagramas must never be worshipped unless it is only one salagrama (when it may be worshipped).

The merit of sipping water in which the salagramas have been washed.
One who sips the water in which the salagrama has been washed in the presence of Vishnu, will be freed from all sins and will eventually enter the realm of Vishnu to abide with him.

The merit that accrues from studying this section on salagrama-characteristics or from listening to it:
O Narada (says Brahma), thus have I explained to you the glory of salagrama; you should comprehend this with devotion, for the sake of pleasing Vishnu.

One who listens to this section which details the merits of salagramas will obtain the four values of life (righteous living, wealth, pleasures and emancipation), and he will be dear to me.

One who studies this text which extols the merits of salagrama day and night, especially during the annual obsequies, will receive untold benefits from whatever he offers to the ancestral spirits.

Having heard this, Narada bowed before Brahma and worshipped him.

Narada says:
You have explained to me, O Brahman, the differentiation of the salagrama-stones, their characteristics and deity-specifications, as also their shapes and colours, which are meritorious or otherwise.

Brahma says:
Listen, Narada, I shall tell you about something which you did not ask: namely, the different effects according to the different colours of the stones.
The salagrama stones occur in many colours: black, blue, yellow, gray, red, tawny and white: they may be ash-coloured. The stones indeed are of numerous kinds. But they must be examined with regard to their beneficent characteristics and only then accepted for worship.
The tawny coloured stone, when worshipped, will kill the worshipper’s wife, while the blue-black stone will bring in wealth. The black stone will cause nourishment and increase of wealth; the white stones will facilitate liberation.
The yellow stone will cause affluence, and the red-coloured one will secure sovereignty, while the intensely red stone will cause death; the extremely black stone will reward the worshipper with celebrity; the ash-coloured stone will cause great sorrow and produce poverty.

Now then, the differentiation of salagrama-deities in accordance with the colours of the stones:
The tawny coloured stone represents Narasimha, the flax-coloured stone Vamana, white-coloured stone Vasudeva and red-coloured stone Samkarshana.
Damodara is represented by the blue-coloured stone, Aniruddha likewise, Narayana by blue-black stones, and Vishnu by black-coloured stones.

Multi-coloured stones indicate Ananta; yellow-coloured ones Sridhara; White coloured ones Vasudeva and stones which are bright-white in colour Adhoksaja.

The stones which are reddish brown like honey represent Brahma.
Thus have I told you, O sage, in great detail about the characteristics of the salagramas.
