The Tarka Sangraha of Annambhatta with his expository gloss on it, called Dipika, is the most popular introductory work on the Nyaya- Vaiseshika system of Indian philosophy. Sanskrit Text, word by word meanings, and commentary.
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
