The human mind, free from the static of restlessness, can perform through its antenna of intuition all the functions of complicated radio mechanisms-sending and receiving thoughts, and tuning out undesirable ones. As the power of a radio depends on the amount of electrical current it can utilize, so the human radio is energized according to the power of will possessed by each individual.
All thoughts vibrate eternally in the cosmos. By deep concentration, a master is able to detect the thoughts of any mind, living or dead. Thoughts are universally and not individually rooted; a truth cannot be created, but only perceived. The erroneous thoughts of man result from imperfections in his discernment. The goal of yoga science is to calm the mind, that without distortion it may mirror the divine vision in the universe.
Radio and television have brought the instantaneous sound and sight of remote persons to the firesides of millions: the first faint scientific intimations that man is an all-pervading spirit. Not a body confined to a point in space, but the vast soul, which the ego in most barbaric modes conspires in vain to cramp.
