From the depths of centuries, the writings of Indian sages have come to us, revealing the innermost secrets of the universe. Works devoted to tantra have always been shrouded in special mystery, which for a long time were inaccessible even to the majority of orthodox Hindus, not to mention foreigners. “Mahanirvana Tantra” is one of the most complex and significant works from the Tantric code. It contains unique instructions on meditative practices and visualizations, logical exercises of a special nature, mantras for concentration and training the mind, Shakta rituals, talks about the system of chakras, or nerve centers, and the place of tantrism in life. The appendix contains images of tantric deities for visualization and their corresponding yantras.
