Thank you for continuing to chant and for continuing to follow the vows you took at initiation. I am grateful that you have understood the importance of these vows. Sometimes when disciples live outside the temple, they become influenced by bad habits of non-devotees, and lose their enthusiasm for the spiritual practices which the spiritual master has requested his disciples to follow in order to remain strong against the allurements of maya. It is for this reason that I am spending so much energy to see that my lectures and books are available for my disciples. It is important that every devotee must seek out a source of spiritual nourishment and maintain connections with that source. Without this connection, it is very difficult to withstand the tests of maya.
