Indriya or Deha Sanyama (Sk.). The control of the senses in Yoga practice. These are the ten external agents; the five senses which are used for perception are called Jnana-indriya, and the five used for action—Karma-indriya. Pancha-indryani means literally and in its occult sense “the live roots producing life”(eternal). With the Buddhists, it is the five positive agents producing five supernal qualities.
