Bhagavad Gita 6.3

आरुरुक्षोर्मुनेर्योगं कर्म कारणमुच्यते।योगारूढस्य तस्यैव शमः कारणमुच्यते॥

ārurukṣormuneryogaṃ karma kāraṇamucyate |yogārūḍhasya tasyaiva śamaḥ kāraṇamucyate ||

For a sage who wishes to attain to Yoga, action is said to be the means; for the same sage who has attained Yoga, inaction is said to be the means.

For the sage who seeks the heights of spiritual meditation, practice is the only method, and when they have attained it, they must maintain themselves there through continual self-control.

Our plain-language meaning of this verse is waiting for scholar review.
