The Gita is not an aphoristic work, it is a great religious poem.
I cannot think of permanent enmity between man and man.
The most practical, the most dignified way of going on in the world is to take people at their word, when you have no positive reason to the contrary.
If you want to change the world, be that change.
The strength of the soul can defy a whole world in arms against it.
You may think your actions are meaningless and that they won't help, but that is no excuse, you must still act.
