Regarding the answers which you gave to Bilas Vigrahadas, they were all correct. When you study very carefully all of the literature which is available, especially Bhagavad-gita As It Is, you will have in your grasp answers to all questions that may be put to you. Please encourage the others to read this Bhagavad-gita at least one chapter every day.
