Bhagavad-gita is not a book on bhakti-yoga for a person only, individual. No. It is meant for the whole mass of people, the whole human society, the leader of the human society or the leader of the family. Everyone should understand Bhagavad-gita very nicely and distribute the knowledge to his subordinates. The father should know the purport of Bhagavad-gita and distribute the knowledge to his sons, daughters, family members. Similarly, the king or the president, he must also know Bhagavad-gita. Just like vivasvan manave praha manur iksvakave 'bravit [Bg. 4.1]. It is not a subject matter that I read it privately and keep it private. It is meant for distribution to the human society. This Krsna consciousness movement is seriously meaning this: that the knowledge of Bhagavad-gita must be spread all over the world — as it is, not with malinterpretation. So that is being done in the Krsna consciousness movement for the benefit of all citizens.
