The book about the great Siddha-yogin Swami Brahmananda Sri Shiva Prabhakara

Swami Brahmananda Sri Shiva Prabhakara Siddha Yoga Para -Mahams - the greatest Siddh, a student of the master of tradition of Siddhi Sri Paambatti. He is a guru in the tradition of Avadhuts, and formally Sannyasin Schuiva-Caula-Siddhant.
Swami Brahmananda was a foolish, radical and detached, master of "crazy wisdom", indifferent to others about him. He lived under different names, not aging, many eras in many places of India, both in the north and in the south. Being a master of secret technology, having the power of moving consciousness, he repeatedly changed his bodies, dissolving each of them in the light. So, having replaced about fifteen bodies, Swami lived for 723 years. Over the years, Swami Brahmananda gave a description of the ancient methods of Shiva Yoga in many texts.
The tradition says that no one can realize Mahasamad-hee on his birthday, but Swami Brahmananda even surpassed this restriction, showing his boundless yogic power. After the dissolution of his physical body in the presence of many of his followers and admirers, Siddh Brahmananda repeatedly came to his chosen students to continue to devote them to secret knowledge, thereby showing them that he surpassed the laws of space, time and death
