To achieve liberation (Kaivalya) one must become keen in developing intelligence (mahat) toward the senses (indriyās). This is known as pratyāhāra. Our natural disposition is for the mind to be consumed by our senses – vision, smell, taste, touch, sound and thought. As a result, we become unhappy, displaced, and lost. This is similar to a child that needs to listen to their teacher to learn but does not. We must listen to ourselves to find happiness/truth. By withdrawing our sense (pratyāhāra), we become sensitive to our inner wisdom (antaraṇga sādhana). When the senses no longer take hold of the mind, we exist in happiness.
