Sri Saligrams is considered the direct symbol of Lord Vishnu, They are found only in Mukti chhetra and Damodar Kunda (north-west of Nepal). According to the religious text of Devi Bhagwate (and other scriptures) to kill demon Jalandhar Lord Vishnu have to destroy Sati Brindha's sati dharma. When he did that Sati Brindha gave four seeming desecrations to Lord Vishnu to become stone, grass, tree, plant. To wash away this reaction Lord Vishnu took four avatars (incarnations). He became stone (Sri Saligram) grass (kush) tree (Pipal) and plant (Tulsi). Since this time the Saligrams are considered to be most auspicious to behold and to worship. The worshipper knows no fear and by Sri Saligram's mercy the worshipper is blessed to attain all desirable things; worldly comforts, good wife, good sons, good health and wealth etc. It is all by the blessings of Lord Mahavishnu that His pastimes are being served. It is an excellent service for devotees of Lord Narayana.
The Saligrams are basically described as fossil-stones and characterized by the presence of discus marks. Saligram-stones (black stones in which fossil ammonites are embedded) are the most celebrated universally. Worship of these stones is widespread and dates back to a distant past. They are worshipped in temples, monasteries and households all over the world, as visible and natural emblems of Vishnu. They are also worshipped in quasi-religious functions like house-warming (grha-pravesa, vastu-puja), pacificatory rites of different sorts (santi), marriages and funerary rituals.

The legend, related at length tells us that Lord Vishnu for benefit of mankind in kaliyuga comes in earth in the form of Saligram and in tulsi tree. Like the worship of Shiva in the form of a Linga, the worship of Vishnu in the shape of a Saligram, is aniconic in character. Saligrams are naturally found in the river Gandaki in Nepal. They are never made by man. In the worship of Saligrams, no initiation is required; there is no special hymnology or specific procedure of worship, nor any need for a qualified priest or master of ceremonies. Worshipped by regular bathing saligram stones in curds, ghee, milk or water will give untold merit and will bestow all the benefits.
Saligram-stones are found only in the river Gandaki, which is a Himalayan stream, celebrated since antiquity as Narayani, Saligrami, Hiranvati and Hiranyavati. The epic Mahabharata speaks of its sanctity (Bhishma-Parva). The Puranas also describe it as a sacred stream in which all the gods and titans abide. By merely looking at it, one would eliminate all his mental dement’s, by touching it his bodily sins are burnt , and by sipping its water the verbal demerits are destroyed. One who comes into contact with this sacred stream will be liberated from the cycle of birth and deaths, even if he be a sinner.
There is a lake at the source of the Kali-Gandaki, called Damodar-Kunda at Nepal. The lower Gandaki is well known as Mukti-Natha-Kshetra, also called Saligrama-Kshetra. The sacred stones are largely found on the banks of Kali-Gandaki near Tukche, between the two mountains Dhavala-Giri and Annapurana. Damodara-Kunda is a Saivite place of pilgrimage. These spots where saligrama-stones are found located within the Nepal territory. Actually there are four spots in the river within Nepal jurisdiction, where the sacred stones are picked up.
Whether one has real devotion or not, if he worships a saligrama-stone with prostration before it, he will surely get emancipated from the cycle of phenomenal existence.
The person who offers a daily service for the saligrama stone will be freed from the fear of death, and he will cross over the stream of births and deaths.
