Tantra is science, tantra is not philosophy. Theories become meaningless experience becomes the center. Philosophy asks, 'Why this existence?' Science asks, 'How this existence?' The moment you ask the question, how?, method, technique, become important. That is the basic difference between philosophy and science. Science is not concerned with why, science is concerned with how. It is not concerned with the 'why' of things, it is concerned with 'how' not with what is truth, but how the truth can be attained. It is not concerned with intellectual problems and inquiries. The word `tantra' means technique, the method, the path. It is concerned with method, with technique - not with principles at all. First, the world of VIGYANA BHAIRAVA TANTRA is not intellectual, it is not philosophical. SUTRA: DEVI ASKS: OH SHIVA, WHAT IS YOUR REALITY? WHAT IS THIS WONDER-FILLED UNIVERSE? WHAT CONSTITUTES SEED?

Some introductory points. Vigyan Bhairav Tantra Chapter 1: The World of Tantra
