Swamiji was born in 1962 in Gujarat state. His spiritual pursuit started at a young age which finally led him to Vedanta.  After completing his education in engineering, he joined a three year course at Baroda in 1986 under Swami Brahmatmananda, a student of Pujya Swami Dayananda Saraswati. He got his brahmacarya-dīkṣā in 1989 and later continued his studies with Swami Visharadananaji at Swami Dayananda Ashram at Rishikesh. During this period, he was privileged to study under Pujya Swamiji.

He was initiated into sannyasa in 1997 by Pujya Swamiji and given the name Swami Sadatmananda.

Swamiji was the ācārya at Arsha Vidya Kendra, Bangalore from 1994 to April 2014. The center was later registered as Arsha Vidya Kendra Trust with Pujya Swamiji as the paramount trustee and Swamiji as the chairman. He conducted classes at the Kendra on Upaniṣads,Brahmasūtra, Bhagavadgītā, Purāṇa, Sanskrit and other texts. He also conducted weekly classes for children and young adults. A lot of people were benefited from his teaching and the various social activities initiated by him in the span of 20 years. His love for studying the śāstra and understanding it in-depth, is a quality that all his students value and strive to imbibe.

From 2011 to 2013, at the invitation of the Mahamandaleswar of Kailash Ashram, Rishikesh, he annually visited Rishikesh and taught Upaniṣads and other texts there, in Hindi with bhāṣyam and ṭīkā.

In 2013, Pujya Swamiji suggested that he conduct the next course at Coimbatore. Accordingly, in May 2014, under the guidance of Pujya Swamiji, a three month course followed by a three year residential course in Vedanta and Sanskrit was started at Arsha Vidya Gurukulam, Anaikatti, Coimbatore with swamiji as the chief ācārya. Swamiji conducted daily classes on the Upaniṣads, Bhagavad gītā, Brahmasūtras and other texts. The course was completed in 2017.

After the completion of the long term course, he conducted some retreats and regular classes on Bṛhadāraṇyaka-Upaniṣad bhāṣyam for about two years.

Later in 2020, Swamiji started a 108 day residential course on Tattvabodha and Bhagavad Gītā which was followed by a two year residential course on Vedanta which concluded in Mar 2022.

Since then, Swamiji has been conducting short term residential retreats, and also daily classes on Vedanta texts at the Gurukulam. In addition, Swamiji is presently conducting an informal course in the traditional gurukulam-style, involving an in-depth study of Vedanta and related texts, for a few brahmacharis selected from the previous course.

Swamiji has been teaching for over 3 decades. He is a very versatile teacher who can reach out to a wide variety of audience both young and old. He is well-versed in Sanskrit and applies it in the study of bhāṣyam. He is committed to convey the message of the śāstra to his students with depth and clarity. His teaching style is simple, clear and with a lot of examples. He can teach with ease in English, Gujarati and Hindi. He is warm, accessible and ready to help. He is very caring of the students and is a great inspiration to them in living a life in keeping with śāstra.

Swamiji has been the Paramount Trustee of Sruti Seva Trust, Anaikatti since the Mahasamadhi of Pujya Swamiji in 2015. He has continued the sampradaya and kept the Gurukulam vibrant with the teaching of Vedanta even while overseeing its daily administration.
