Vaitalik Bhanumati ka Pitara aur Kalika Kulluka Tantra is a mystical Hindi book that serves as a compilation of ancient mantra, tantra, and spiritual knowledge often referred to as a “wonder casket.” The book, published by Randheer Prakashan Haridwar and authored by Bhanumati Das with contributions by Swami Surendra Das ‘Nirvaan,’ draws on centuries‑old handwritten bhojpatras of mantra vidya. It includes a variety of esoteric practices and mantras — such as Vashikaran, Nrsimha mantra, Yakshini chants, khechari vidya, and methods for diagnosing difficult ailments — promising deep spiritual and practical insights. The “Kalika Kulluka Tantra” portion explores ritual methods and the disciplined chanting of powerful mantras of deities, framed within traditional tantric practices. Presented as a treasure chest of occult knowledge meant to reveal hidden powers to earnest readers, the book blends mystical adventure with practical mantra application rooted in Indian tantric tradition.
