Krishna provides a brilliant developmental roadmap for the spiritual practitioner. For the neophyte sage who is just beginning to climb the ladder of Yoga (ārurukṣor muner), active physical work and duty (karma) is declared to be the cause, instrument, or means (kāraṇam ucyate). However, for that exact same person, once they have successfully climbed and become elevated and established in Yoga (yogārūḍhasya tasyaiva), total serenity, stillness, and the cessation of disturbance (śamaḥ) is declared to be the means (kāraṇam ucyate) to progress further.
