I am very pleased to learn that both you and your wife have been lecturing on Krishna Consciousness at the George Washington University and there was good response to your program. You simply read our books and if you simply reproduce the purport of Srimad-Bhagavatam or Bhagavad-gita, people will take it very seriously.
So, of course, you must understand the purport and reproduce it in your own language. That will be very good, but someway or other if in some way you present the purport of Srimad-Bhagavatam or Bhagavad-gita that will be also very good.
The idea is that we should not make any addition or subtraction of mental speculation, but we should endeavor, even if we do not fully understand from our present platform, to present simply the philosophy as we have received it directly and realized it by practical experience.
