Stand not a beggar before the door of science seeking power that kills more than heals. - Sivananda Saraswati

There can be fear only where there is duality. How can there be fear for one who experiences non-duality? Such a person is the most courageous of men. The courage of a soldier in the battlefield or of a dacoit is only Tamasic courage. It is not courage at all. It is only brutal ferocity born of hatred or jealousy. That Sattvic courage born of Wisdom of the Self alone is real courage.

Yoga is the science that teaches you the method of uniting the individual will with the Cosmic Will. Yoga transmutes the unregenerate nature and increases energy, vitality, vigour, and bestows longevity and a high standard of health. Try to increase the power of concentration. Japa will help you to have a one-pointed mind. (What Is Actual Yoga)
