According to Osho, sadhana is split into vairagya (a spontaneous, passing mood of dispassion) and abhyasa (deliberate, repeated remembrance) because insight alone is fleeting. Life gives momentary glimpses, but the mind’s lifelong conditioning erases them. Abhyasa gathers, preserves, and deepens those flashes until dispassion becomes a carved groove, a witnessing power that restrains the mind and brings real transformation.
You get brief wake-up moments that chasing things won’t satisfy you, and abhyasa is practicing that insight over and over so it stays and changes you.
