Paramahansa Yogananda : (2) " The happiness of one’s own heart alone cannot satisfy the soul; one must try to include, as necessary to one’s own happiness, the happiness of others. " - Paramahansa Yogananda " A true yogi may remain dutifully in the world; there, he is like butter on water and not like the easily-diluted milk of unchurned and undisciplined humanity. " - Paramahansa Yogananda
