The Bhagavad Gita's Opening Speech to Arjuna

Bhagavad Gita offers insight into why any of us should ever undertake any action at all. Krishna begins with the most obvious tactic, he tells Arjuna to stop being a wimp or actually to stop acting like a eunuch. The true self is invulnerable, swords do not cut him, fire does not burn him,. water does not wet him, wind does not partch him. But here in the Gita Krishna gives it short shrift, stating that complete inaction is simply an impossibility.
