Salagramas do not require preliminary rituals of purification and consecration. They naturally contain the vibhuti of the Godhead, and may be worshipped straight away.
In the worship of Salagrama, no initiation is required; there are no special hymns or specific procedure of worship, nor any need for a qualified priest or master of ceremonies. Worshipped anyhow, it bestows the benefits; and there is no error of any kind.
If, however, it is formally worshipped with all the details scrupulously observed, the benefits procured are boundless.
Method of worship:
In the morning after bath arrange your prayer vessels after cleaning them. Fill a pot with water mixed with few drops of Gangajal or rosewater. Set up oil lamp, incense sticks and fresh flowers and sandal paste. Place the sila on the plate and perform abhishek (pour water) on the sila chanting "Om Namo Narayana". Now lift the shila, wipe it with a soft cloth and place it on the seat. Apply sandal paste as a 'Tilak' and offer fresh flowers. Offer a few leaves of Tulsi or encircle a tulsi mala around Him. Light incense and oil lamp and also camphor and offer to Shree Narayana one after the other. Offer a fruit or sweet as Naivedyam to the Lord.
Chant the Shaligram mantra below:

I bow to Lord Vishnu the one Master of the Universe, Who is ever peaceful, who reclines on the great serpent bed, from whose navel springs the lotus of the creative power, who is the supreme being, who supports the entire universe, who is all-pervading as the sky, who is dark like the clouds and has a beautiful form; the Lord of Lakshmi, the lotus-eyed one, whom the yogis are able to perceive through meditation, He, who is destroyer of the fear of samsara.
Offer gratitude to Lord Vishnu for arriving in your home and blessing you and your family always.
Om Shantih Shantih Shantih !!!
This method of worship is easy to follow and applicable in our day to day life routine. In case you are unable to worship every day, just offer Obeisance (Namaskar) to the deity before leaving for work/ starting the day. His presence alone is a guarding and protective force in your home, bringing along happiness and abundance.
