By Swami Harshananda
Indriyadhāraṇā literally means ‘restraining the senses’. It is holding back of the sense organs and their activity.
Yoga is a perfect concentration of the mind ultimately leading to the union of the jīva with Paramātman. This concentration can be attained only when the senses do not function actively giving rise to mental quietude or tranquility and holding back of the sense organs and their activity is referred as Indriyadhāraṇā.
