Meditation: Its Process, Practice, and Culmination
Swami Satprakashananda
A practical approach to the path and practice of meditation. Included in this study are meditations the swami directed during his scriptural classes, an examination of the four yogas, and a discussion on their culmination in the realization of the non-dual Brahman.
My child, what I want is muscles of iron and nerves of steel, inside which dwells a mind of the same material as that of which the thunderbolt is made.
-Swami Vivekananda
