Yogananda: The Science behind Meditation

The greatest of all things is to remember that scientific meditation means the withdrawal of current from the nerves, and .when you can do that, then sensations cannot reach the brain, and sensations cannot rouse perceptions and associated thoughts. Concentration and meditation both have two sides. (1) Disengage the attention from objects of disturbance and (2) put the attention on one object at a time. In the beginning you cannot make your attention stay on one thing. After you have attained that stage wherein you can control attention then you will find that you can accomplish much in the spiritual line or the material line.
