Astroshastra offers an exotic and rare collections of Shaligrams (saligram, saligrama or shalagrams) from Gandaki river in Nepal. Shaligram represents a natural form of Lord Vishnu. Shaligrams are worshiped in temples and households all over the world for the blessings of Lord Vishnu and goddess Lakshmi.

The Salagramas are specifically described as fossil-stones which have taken shape in the Gandaki-river, and as characterized by the presence of discus marks (‘gandakyudbhava-vajra-kita-krta-chakra-samayukta-sila).

Salagrama stones are obtained only from the river Gandaki, which is a Himalayan stream, celebrated since antiquity as Narayani, Salagrami, Hiranvati and Hiranyavati. The epic Mahabharata speaks of its sanctity (Bhishma-parva): it contains in itself the waters of all the holy-rivers (Vana-parvan, 84, 113), and it is the abode of Agni, the fire-god.

Krishna, Arjuna and Bhima are said to have crossed this river on their way from India-prastha to Girivraja. The puranas also describe it as a sacred stream in which all the gods and titans abide (‘punyodaka surasura-nishevita’). By merely looking at it, one would eliminate all his mental defilement’s, by touching it his bodily sins are burnt up, and by sipping its water the verbal demerits are thrown out.

By worshiping Maha Vishnu in the form of shaligrama , one gains the merit of performing a thousand Rajasuya sacrifices.
