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.
Seek ye first the kingdom of God, and everything else shall be added unto you. This is the one great duty, this is renunciation. Live for an ideal, and leave no place in the mind for anything else.
-Swami Vivekananda
