Bhagavad Gita Chapter 6.3
ārurukṣor muner yogaḿ
karma kāraṇam ucyate
yogārūḍhasya tasyaiva
śamaḥ kāraṇam ucyate
Translation
For one who is a neophyte in the eightfold yoga system, work is said to be the means; and for one who is already elevated in yoga, cessation of all material activities is said to be the means.
