06. Sadhana through Meditation
Fragment ID: 1403
Chit is the pure consciousness, as in Sat-Chit-Ananda.
Chitta is the stuff of mixed mental-vital-physical consciousness out of which arise the movements of thought, emotion, sensation, impulse, etc. It is these that in the Patanjali system 


have to be stilled altogether so that the consciousness may be immobile and go into Samadhi.
Our yoga has a different function. The movements of the ordinary consciousness have to be quieted and into the quietude there has to be brought down a higher consciousness and its powers which will transform the nature.
