BG Chapters 1 - 6

BG 2.11, Purport:

Arjuna argued that religious principles should be given more importance than politics or sociology, but he did not know that knowledge of matter, soul and the Supreme is even more important than religious formularies. And because he was lacking in that knowledge, he should not have posed himself as a very learned man. As he did not happen to be a very learned man, he was consequently lamenting for something which was unworthy of lamentation.
