Series 1, Chapter 10 pg 101, Para 3: If this is done, then it becomes possible to move among the objects of sense, in contact with them, acting on them, but with the senses entirely under the control of the subjective self, — not at the mercy of the objects and their contacts and reactions, — and that self again obedient to the highest self, the Purusha. Then, free from reactions, the senses will be delivered from the affections of liking and disliking, escape the duality of positive and negative desire, and calm, peace, clearness, happy tranquillity, atmaprasada, will settle upon the man. That clear tranquillity is the source of the soul's felicity; all grief begins to lose its power of touching the tranquil soul; the intelligence is rapidly established in the peace of the self; suffering is destroyed. It is this calm, desireless, griefless fixity of the buddhi in self-poise and self-knowledge to which the Gita gives the name of Samadhi.
