For example, yoga enables one to solve all problems by soul guidance, the wisdom born of Self-realization. So long as problems occupy the mind, there is little opportunity for mental and spiritual freedom, for these cannot coexist with mental turmoil. The mind should be cleared of confusing moods, worries, and fears so that in the sky of mental calmness the liberated bird of paradise, the soul, can soar and spread its wings over one’s whole existence. By gradually easing the perplexities and difficulties that burden one’s life from within and without, yoga paves the way to freedom. - Paramahansa Yogananda.
