Abstract
Indian spiritual and philosophical systems are essentially cognitive scientific in nature. Having origin in the Upanishads all Indian philosophical systems supplemented and complemented one another to develop a comprehensive source book of cognitive science. The nature and form of consciousness, mind and its functions are extensively dealt with and discussed from Upanishads through Buddhism, Jainism, Viseshaka, Nyaya, Yoga, Samkhya, Poorva Meemamsa,and Uttara Meemaams, Sabdabrahma Siddhanta contributing to many concepts which have relevance to cognitive science and language acquisition and communication. In this paper all these will be reviewed and especially the concept of guṇa as envisaged in various Indian philosophical systems will be presented and correlated. The evolution of concept of guṇa through Shaddrarsanas will be specifically looked at. A correlation with Sabdabrahma Siddhānta of Indian grammarians initiated by Patanjali and developed through Bhartruhari will also be presented.
