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.
The less passion there is, the better we work. The calmer we are, the better for us and the more the amount of work we can do. When we let loose our feelings, we waste so much energy, shatter our nerves, disturb our minds, and accomplish very little work.
-Swami Vivekananda
