Tarka is an Indian system of logic which is a fine and precise tool for the philosopher who probes to discover the Ultimate Truth. The Tarka-samgraha, with its expository gloss called the Dipika, by Annambhatta is the most popular introductory work on the Nyaya-Vaisheshika system of Indian philosophy. While this text is meant primarily to unlock the doors of the twin-darshana of Nyaya-Vaisheshika, it is also the master key that has been used by the Acharyas of the other darshanas.
Swami Virupakshananda, who was a senior scholarly monk, has lucidly translated this text for the English readers to appreciate the traditional philosophical systems.
