Bhagwat Geeta Chapter 1 Shlok 7

“The worthiest of the twice-born.” That is how Duryodhan
addresses his teacher Dronachary before he introduces to him the chiefs
of his army. “The worthiest of the twice-born” would hardly be an
appropriate term of address for a commander-in-chief if the war were a
physical, external war. In fact, the Geeta dwells upon the conflict between
contradictory innate impulses, upon the dual conduct which is
Dronachary. The world of matter exists and there is duality if we are
even in the least isolated from God. However, the urge, too, for
overcoming this duality of object-spirit is derived first from the teacher
Dronachary. It is imperfect knowledge that induces the hunger for
enlightenment.
It is now time to have a look at the leaders of the impulses which
are hostile to the essentially sacred character of the Self.
