A lucid exposition of the wisdom enshrined in the Vedas, the Upanishads and the Bhagavad Gita together with a chapter on the general features of Indian philosophy.
Avoid excessive merriment. A mind in that state never becomes calm; it becomes fickle. Excessive merriment will always be followed by sorrow. Tears and laughter are near kin. People so often run from one extreme to the other.
-Swami Vivekananda
