Mesmerized by Pujya Swami Chinmayananda in the 1960s, Brahmachari Raghavan served Pujya Gurudev as his traveling secretary for a few years. After completing his Vedanta course in Mumbai, he traveled to Taiwan, where he successfully managed his own business and taught Vedanta part-time. He was instrumental in founding CM in Hong Kong and Taiwan.
In 1992, he received sannyasa diksha from Pujya Gurudev and became Swami Shantananda. Since then, Swamiji has dedicated his life to Mission work and Vedantic teachings, and is presently the resident acharya of Chinmaya Mission New Jersey.
As a speaker, Swamiji's talks are filled with wonderful insights into life and people respond instantly to his wisdom and affectionate nature. In 2001, as his personal tribute to Pujya Gurudev, to commemorate the 50th-year celebrations of Chinmaya Mission, Swamiji undertook and completed 50 Gita jnana yajnas all around the world.
