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.
Work unto death -- I am with you, and when I am gone, my spirit will work with you. This life comes and goes -- wealth, fame, enjoyments are only of a few days. It is better, far better, to die on the field of duty, preaching the truth, than to die like a worldly worm. Advance!
-Swami Vivekananda
