Ratna Sangamam is a community service project of O.S. Arun. The basic motive of the project is to visit Old age homes / orphanages / Children with Autism / under privileged Children, interact with them and perform free for them. During this event, Arun also provides food and basic requirements for these people within his capacity to support. The response has been very successful and is very satisfying. We have so far had 10 Events covering places including Chennai / Tanjore / Chengalpet / Kaduveli (a village near Tanjore).
