With the turbulence produced by the outgoing senses, the mind will naturally lose its peace and stability. Instead of allowing the senses to overpower it, the mind must overwhelm the sense objects. For this, the seeker should reflect constantly upon the Soul and gain adequate inner spiritual strength. As the mind gets sufficiently sublimated and strengthened, its influence will be felt on the senses. The purpose of all the elaborate instructions about the Soul is only to enlighten the buddhi and strengthen the mind.
