By Paramahansa Yogananda
Sit upright, shoulder blades together, chest out, abdomen in, hands at the junction of thighs and abdomen. concentrate at the point between eyebrows, where one can enter the state of super consciousness. Forget the body, forget the surroundings, earth, sun, moon stars, thoughts feelings and forget all perceptions. Feel only one goal of perception--the vastness that you wish to perceive within yourself. Repeat to yourself: "I am infinite," Go on mentally affirming this until you feel that you are everything and beyond everything, Say: "I am timeless, I am spaceless, I am beyond the body, thought, and speech; beyond matter and mind. I am spaceless, I am Infinite Blessedness."
Meditate on that.
