Preaching as a university student

You are asking what should your preaching work be now that you are attending
the university. So the first preaching work is that yourself should become
an ideal devotee. Lord Caitanya said that one should first make himself
perfect and then attempt to instruct others. There is no point in telling
another man to stop smoking if you yourself are smoking cigarettes. Even
though you are mixing with all kinds of the student class at the university,
you must strictly refrain from the four prohibitive sinful activities, and
as an initiated student you must not let a day pass when you do not chant at
least 16 rounds of Hare Krsna Mantra. If you can follow just these things
nicely that in itself will be strong preaching by behavior. You should also
always wear Kunti beads around the neck and wear the marking of tilak.
People will inquire from you and you can tell them about Krsna Consciousness
and sell them books also.
You should also try to associate with the devotees in England and Scotland.
If possible, visit the temple on Sundays and whenever you can, and always
read my books.
