The Hindu Perspective

In one sense, we are all mentally afflicted, in the sense that everybody's mind is illusioned by some desire or ambition. Whatever our desire or ambition, our mind carries our self to a next life that will facilitate fulfilling that desire. The Bhagavad-gita describes yoga as that process by which we free the mind from all conditioning and all illusions. So even the mentally ill or disabled can perform this yoga. The speaker of Bhagavad-gita describes the yoga to be engaging all the senses including the mind in focusing on the Absolute Truth by kirtan (Sanskrit term for chanting of God's names).
