Vigyan Bhairava Tantra description

'Vijnana' or 'Vigyana' means consciousness, 'Bhairava' represents Shiva, and 'Tantra' means technique or method.
Or in other words, it can be said Shiva's Techniques for Consciousness.
This book is a discourse between God Shiva and his consort Devi or Shakti.
It briefly presents 112 meditation methods or centering techniques (dharana).
These include several variants of breath awareness, concentration on various centers in the body, non-dual awareness, visualisation and contemplation through each of the senses.
A prerequisite to success in any of the 112 practices is a clear understanding of which method is most suitable to the practitioner.
