Santhi was always interested in wise men and Masters. He travelled far and wide spending sleepless nights meeting great spiritual masters and listening to their teachings. He spent years, travelling to the Kodachadri mountains, Gokarna, the Chamundi hills of Mysore, Agasthya koodam, the deeper jungles of Western ghat mountains and the great Himalayas.
His unquenched fire for inner search lead to the creation of ‘Viswa Santhi Mission’ with Raja Yogi Atmaram in 1982. In 1984, Santhi also founded ‘The Centre for Conservation of Humanity’ with his friend Raman Nair and a few other close associates. He was actively involved in the protection of nature and humanity.
During this long spiritual search and the many pilgrimages in India, he came across many remarkable people, known and unknown spiritual Masters. He received direct spiritual teachings from Maharishi Mahesh Yogi, Madhavan Pillai Swami, Guru Vasuki, Ramananda, Balakrishna Pillai Swamikal, Shri. Krishna Adiga, Shri.

Though Santhi has been with many masters, he considers Shri. Bhaskara Pillai Swamikal as his spiritual mentor. He met Bhaskara Pillai Swamikal on Guru Purnima, a day devoted to the Masters. Santhi recollects his meeting with him,
“Swami was quite ordinary in his ways and we remained awake the whole night. He was talking about Pranic Spandana (Pulsations), Spandana Upanishad and its significance in the spiritual evolution of a seeker. By sunrise, I went along with him. From that moment onwards I have never felt the need for another Master and I have stopped hunting for Spiritual Masters.”
