T.K Thangarajan was a successful businessperson managing his cotton industry in Tiruppur in Coimbatore. He was into politics and a movie producer too. He read the works of Ramalinga Adigal and hosted gatherings every Wednesday at his home. He became a disciple of Chitramuthu Adigal and came to be known as Thaaiveedu Thangarasan. He became a devout follower of Agathiyar and the Siddhas. Tavayogi saw the worst of times when his business collapsed as a result of politics in India in that period of time. He had to hit the streets with his family; became blind overnight, and was on the verge of jumping onto the railway track when a voice told him to have faith in Agathiyar. He formed a determined resolve to belief in Agathiyar and let Agathiyar rule his life as he (Agathiyar) pleases. He regained his sight. His life picked up and he regained his lost treasures only to leave them all behind voluntarily when he turned 50. He walked out of his family and all the luxuries he had accumulated in this time becoming a traveling mendicant. His travels saw him reach Rishikesh. Soon he spent years in the caves of Kutralam, Pon Uthiyur, and finally at Sathuragiri. After spending 8 years in Sathuragiri he was directed by Agathiyar to seek a place known as Agathiyar Vanam and start an ashram. He located it at Kallar. Soon Agathiyar directed him to Malaysia where both his guru Chitramuthu Adigal and Paramaguru Jeganatha Swamigal had been. He took up the dictate of Agathiyar in 2004 following an Indian citizen working in Malaysia. But he found himself left stranded on the streets of Kuala Lumpur. Tavayogi contacted the only reference he had in Malaysia, one Soundarajan. Soundarajan took him in. Tavayogi found his way to Lord Perumal’s temple in Puchong where he gave his first talk on the Siddhas in Malaysia. After meeting Appana Nagappan in Kallar, Tavayogi traveled again to Malaysia in 2005 at his invitation to officiate the opening of an affiliate of Tavayogi's, the Sri Agathiyar Gnana Peedham at Wisma Keringat in Batu Caves, Malaysia. I met Tavayogi for the first time at this premise. When the Tamil dailies carried news about the opening of the Agathiyar Gnana Peedham in Malaysia by one Tavayogi Thangarasan Adigal daily, the name Thangarasan appeared familiar to me. I recalled seeing that name on a leaflet given to me during my very first Nadi reading by Nadi Guru Senthilkumar some 4 years back. I had kept the leaflet with me. I looked for it and headed to the local peedham after calling them up. Tavayogi confirmed the leaflet was his. Tavayogi accepted me as his disciple the same day and initiated me and my wife officially into the worship and path of the Siddhas. Thus began a beautiful relationship between a guru and a disciple.
I am indebted to him for showing me to Agathiyar, and bringing me to all the caves, samadhis, temples and abodes of the Siddhas. In bringing me to these places he officially showed me Sariyai that I had picked up from my parents. Introducing me to Kriyai, he got me started on doing the homam or fire ceremony. He started me on doing charity, beginning with my first Annadhanam at his Kallar ashram. He officially showed me Yoga that I had previously picked from books. He officially led us into Gnanam by passing us two of his books that are acclaimed by both Agathiyar and Ramalinga Adigal - "Andamum Pindamum" and "Atma Darisanam". What else could one ask of his guru?
