Bhagavad Gita · Chapter 3: The Path of Action

Bhagavad Gita 3.19

tasmādasaktaḥ satataṃ kāryaṃ karma samācara | asakto hyācarankarma paramāpnoti pūruṣaḥ ||

Therefore always do the work that has to be done, without attachment. By acting without attachment, a person attains the Supreme.

Modern context

Here is the practical conclusion: always do the work that ought to be done, without attachment. Krishna makes a striking claim for it: by action done in this way a person reaches the highest. There is no need to wait for a different life in order to begin. The work in front of you, done rightly, is the path.
