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.
All power is within you. You can do anything and everything. Believe in that. Do not believe that you are weak; do not believe that you are half-crazy lunatics, as most of us do nowadays. Stand up and express the divinity within you.
-Swami Vivekananda
