The author, Dr. K.V. Raghupati, through this booklet attempts to create awareness of mudras, or 'yoga through hands' as he calls it. While it may be difficult for the aged or the sick to practise asanas and even pranayama, anyone anywhere can practise these simple yet powerful mudras to rejuvenate the energy levels and recover from the many of the illness afflicting the body and mind.
Be strong! ... You talk of ghosts and devils. We are the living devils. The sign of life is strength and growth. The sign of death is weakness. Whatever is weak, avoid! It is death. If it is strength, go down into hell and get hold of it! There is salvation only for the brave. None but the brave deserves the fair. None but the bravest deserves salvation.
-Swami Vivekananda
