Although the place where it is located has been inundated, the Ramakrishna Math has undertaken relief work across Chennai, distributing food and clothes to the needy.
Volunteers of the math, located in Mylapore, a low lying area, have served hot cooked food to 1,500 people in Ganeshapuram area and 500 in Mint area.
The volunteers also distributed 150 blankets, milk powder and water packets, Sri Ramakrishna Math said.
Swami Vimurtananda, the math's manager, said cooked food was distributed among 6,000 people in areas close to the sea - Pattinappakkam, Srinivasapuram and Nadukuppam.
Food was distributed among 4,000 people with the financial support of devotees in the areas of Ramakrishnapuram, PNK Gardens and Sundaragramani and Slaterpuram, he said.
The unprecedented rains in Chennai triggered massive floods, inundating large parts of the city. The floods in Chennai and three other districts in Tamil Nadu have claimed over 325 lives.
