(Vijñāna Bhairava Tantra): This classic but brief Tantric text constitutes a collection of purely monistic teachings, in which Bhairava (Shiva) describes 112 ways to enter the universal and transcendent state of consciousness. Traditionally regarded as a manual for masters, the Vijnana Bhairava Tantra is a practical work and a comprehensive aid to students of meditation from any tradition, since it deals with the profound underlying principles of spiritual practice and contains a vast library of techniques ranging, from elementary to advanced.
