Meditation is a powerful mental and nervine tonic. The holy vibrations penetrate all the cells of the body and cure the diseases of the body. The powerful, soothing waves that arise during meditation exercise a benign influence on the mind, nerves, organs and cells of the body. The divine energy freely flows like the flow of oil from one vessel to the other, from the feet of the all-pervading Lord, to the different parts of the body of the aspirant. Through regular practice of meditation build around yourself a strong fortress of protection against the evil forces of the ignorant world and robe yourself with a magnetic aura. ~ Swami Sivananda
