For many years I have emphasized the importance of reading Srila Prabhupada's books. For those who are genuinely interested in going deeply into Krishna consciousness it is essential. Wherever he was, whether in LA or Vrndavana, Srila Prabhupada said how important this was:
"We can read about Krsna whole life, such big literature. Whole life. If you read twenty-four hours daily-that you cannot-still, you have to devote your whole life to finish this literature."
(From a Los Angeles lecture, December 25, 1973)
