When your intelligence, flung by the conflicting views of scriptures, becomes steady and stable within, then will you attain yoga, the spiritual communion.
Link this verse with the one on vyavasāyātmikā buddhiḥ (2.41). Yoga-siddhi is verily the resolute nature of intelligence, its unflickering state.
When thus inner stability and poise come to be, stop all efforts and seeking. This is itself the goal, the state to be experienced, realized.
This is when the Consciousness animating and activating the body, functioning as mind, intelligence and ego, suspends all functioning, it reveals its own sublime nature, content and character.
Yoga is no other than this kind of inner poise, stillness and absorption. Do not look for any other Self. Discern the outcome well and be settled inwardly.
Various notions about the Self serve only to distract the mind. The real yoga is the unswerving state of the intelligence. Do not look for anything else!
