Regarding your questions about details for Deity worship, I have already mentioned in a previous letter that I shall teach you these things when I arrive in London. In the meantime there is no necessity for you to increase Deity worshiping. For the time being these new Deities may be put away nicely until I personally install Them and instruct you very nicely how to tend for Them correctly. For the present you may join Sankirtana Party because I know that your presence will enliven everyone. Actually, temple worship is for the neophyte devotee, and the preacher is in a higher position than the neophyte. That is the definition given in Srimad-Bhagavatam. The advanced devotee should be very much enthusiastic in preaching the transcendental message of Lord Caitanya, and temple worship should be entrusted to the newcomers, or neophytes.
