Lol!All of Krishna's exposition of Nishkámya karma to Arjuna was only to prepare him to kill all his relatives dispassionately, without compunction or remorse.
All of us also know how the ideal brahmins should be which we aren't and also that our future generations will be still further from that ideal than we are. The least we can do is make thei future better for them by coming together and devising some programmes for it. First as a community wirh same interests and goals, not just as flag bearers of brahmin dharma.
Is that all your understood from the Geeta?
Making it sound as if Krishna was just preparing Arjuna for an external Jihad.
Geeta is Universal..its message is for entire mankind to improve and evolve.
The Geeta isnt a killing manual.
