Untrained warriors are soon killed on the battlefield; so also persons untrained in the art of preserving their inner peace are quickly riddled by the bullets of worry and restlessness in active life.
Paramahansa YoganandaWhen a man in the process of dreaming becomes conscious that he is dreaming, he is no longer identified with the phenomena; he is not affected exultantly or dolefully. God consciously dreams His cosmic play and is unaffected by it's dualities. A yogi who perceives his real self as separate from his active senses and their objects never becomes attached to anything. He is aware of the dream nature of the universe and watches it without being entangled in its complex but ephemeral nature.
Paramahansa YoganandaNo matter what you are doing, keep the undercurrent of happiness. Learn to be secretly happy within your heart in spite of all circumstances.
