It has been a custom since time immemorial that a person born in a brahmana family must.worship the salagrama-sila in all circumstances. In our Krsna consciousness society, some of the members are very anxious to introduce the salagrama-sila, but we have purposely refrained from introducing it because most of the members of the Krsna consciousness movement do not originally come from families of the brahmana caste. After some time, when we find that they are actually situated strictly in the line of brahminical behavior, this salagrama-sila will be introduced.

In this age, the worship of the salagrama-sila is not as important as the chanting of the holy name of the Lord. That is the injunction of the sastra.

harer nama harer nama
harer namaiva kevalam
kalau nasty eva nasty eva
nasty eva gatir anyatha
