Both work. Action is better.

Giving up action and the yoga of action both lead to the highest good. But of the two, acting in yoga is better.

What it means

Krishna answers directly. Both paths lead to freedom. Renouncing action, and karma yoga, acting without attachment. But karma yoga, he says, is better. Not because renunciation is wrong, but because acting with a free heart is more natural and more possible for most people.

The story

For a warrior standing in his chariot, this answer matters. Krishna isn't asking Arjuna to become a monk. He's saying the better path is right here, doing his duty with a free heart.

In your life

Think of someone who wants to quit everything and move to a retreat centre. A wise friend says, try bringing peace into your actual life first. Before you escape, try doing your daily work in a new spirit.
