Entering Srila Prabhupada's quarters was always an enlightening experience. Sometimes Srila Prabhupada sat and read His books. Whenever He read it seemed as if someone else had written His books because He didn't read with the mind of an author who might be looking for editing mistakes or grammatical errors. He read them with the relish of a pure devotee reading the pastimes of the Supreme Lord to whom He was completely attached.
One day in Los Angeles I went into His room to perform my duties and He was sitting and reading "Bhagavad Gita As It Is". After I offered obeisances He looked at me and said, "If you just read this one book and understand, you will become Krishna Conscious in this very life."
A few months later when I went into His room, He was reading "Nectar of Devotion". He looked at me and said, "This book is so nice. Just by reading this one book you can become Krishna Conscious."
Srila Prabhupada teaches us by example. He does everything He asks us to do. He requests us to read His book and He does, too.
