Most people want to meditate but do not know how to do so. The purpose of meditation is to connect the little joy of the soul with the vast joy of the Spirit with focused practice.
Meditation is not the same as concentration which consists in freeing the attention from objects of distraction and focusing on one thing at a time. Meditation is that special form of concentration in which the attention has been liberated from restlessness, and is focused on the Infinite, to be focused only on God or sacred thoughts and ideas.
Meditation consists in certain physical, psychological, and metaphysical processes — by which the static of restlessness can be removed from the body, mind, and soul radios, which can then be tuned in with the Infinite. By calm, continuous, one pointed attention the ego must be kept connected to the Spirit until they both become merged into everlasting bliss.
In this book Yogananda gives some concrete metaphysical methods of meditation, for the student who has already struggled through the mobs of rowdy thoughts and crossed the portals of silence. The instructions will be found in the various sections of the book preceding each type of meditation: prayers or demands addressed to the Divine, affirmations about God, and those spoken to the individual consciousness.
