"Cold depression is like the black on the back of a candle burning in a glass container." It is a hypnotic numbness and takes effort to wake up out of the hypnosis. Align with your dharma through service, service that is beyond your personality. " Where there is dharma, there is no karma." Yogi Bhajan says when you are transactory, you will always fail. If you are resurrectory, then you get back up and you will always succeed. It is universal law.
Full yoga kriya includes 4 minute meditation.
