Swami is a completely focused person, who talks intensely and passionately about his philosophy and knowledge. He lives a simple life, and certainly practices what he preaches, and seemingly has no desire, other than to communicate. He has written 5 books in local languages about his experiences.

Childhood and spiritual journey:
Sri Sadashiva Yogi was born in 1933 in South Indian district of karnataka at Gubbi. In 1953 he renounced at a young age, the worldly ways, in search of the infinite life force. It lead to endless journey all over including the Himalayas, meeting with scholars, learned men and yogis. None of them including his meeting with P C Sarkar had any help in helping him understand the truth of journey of life.
Meeting his Guru:
But he never gave up his rational, human perspective and completely non conformist attitude to life. Later as destined, he met Sri Nityananda Swamiji, it completely altered the journey and goal of spiritual life. For some time he settled down as a Mouni Swami (Silent Monk) in Rishikesh. Later he resided at Hampi, in the well known Shivananda Yogaashrama till his Mahasamadhi on September 17, 8AM 2021.

Philosophy:
Swamji brings a deep awareness of science of spiritual knowledge, in the tradition of Siddha Yoga. Further has fought all kinds of superstitions associated with religion and so called religious masters. He carries a deep fervour of a scientist to unravel the mysteries of nature and life to communicate with ordinary men and women including educated class. He met with people from all walks of life, as a practising homeo-therapist.
“Life is like Air-filled bubbles floating on water. No more than that. There is no difference between big or small bubbles. Nobody knows when they will burst and what may happen next.” Sadashiva Yogi
Recollections of Sri Siddhayogi Dr. Swamy Antarmukhananda:

In Sri Guruji’s words: “A co-siddha yogi and junior contemporary of Swamiji Sri Sri Sri Ramananda Paramahamsa attained samadhi September 17th at 8AM IST of 2021 at Hampi Ashram.
He is simple and great sadhaka visited ashram twice after Swamiji’s samadhi. He used to scold Badagara siddha vidyardhies like our Swamiji for not doing yogam properly. He is highly principled but Nastika at one time.
He praised us both for serving Swamiji. He used to do yogam without sound and taking more water. Then I objected him for both. He designed his method of doing yogam which is not traditonal as he is an athiest. Once he commented on me as sinless one డాక్టర్ నిరఫరాధి. He is known for his simplicity and selfless brahmachari
A conversation between Him and Swamiji which he used to tell me when he asked Sri Swamiji “ why do you do gurupuja and all these things which are external” Then swamiji replied and scoleded him “పోరా పిచ్చివాడా ప్రపంచం గురించి నీకేమి తెలుసు? గురు భక్తి లేనిదే ఎవరూ రానించ లేరు” Translation: Oh silly person, what do you know about this world? Without Guru Bhakti no one can succeed.
He wrote some books and sent copies to me.
I objected some points for commenting Swamiji and telling some unscientific unscriptural basics and sent thru disciples. He realised doctor is not an ordinary doctor and requested me to give speech in his presence. I delivered lecture at Mamidada ashram in his presence. He called upon our devottees to attend along with me. Two devotees took online from that village. He followed siddha sampradayam smply wearing white clothes. But our Swamiji ventured to streamline our vidya into brahma vidya sampradayam.”

Om Tat Sat!
