His Holiness Swami Haridhos Giri popularly known as Guruji was the chief disciple of Swami Gnanananda Giri of Thapovanam.

 He formed GA Trust in the year 1984.  

Objectives of the Trust

• To spread the spirit of Namasankirtana worldwide.
• Guruji’s aim was to create a full-fledged ashram complex to house Sri Pandurangan Rakhumayi temple, a Shrine for Sathguru Gnanananda, the Mahashodasi temple, the Meenakshi Sundareswarar temple and other social welfare projects. These were fulfilled with Samprokshanam of the shrines in the year 1996.
• A great hall called Namasankirtana Mandapam has been constructed where Bhajan sessions are held regularly.
• As part of its social welfare objective, the GA trust built a hospital known as the “Guruji Medical Centre & Hospital”, which has become lifeline for Thennangur and other surrounding villages.
• A Library is also maintained.
• The trust maintains Gosala for Gosamrakshanam, Veda Patasala and A Home for Senior Citizens.
