Thanks to Smt Meera Ganesan and Smt Saraswathi Thyagarajan mami for sharing these with all of us.
Smt Meera had underwent serious eye problems in the past and purely on Mahaperiyava’s blessings, she recovered from them. Periyava had apparently given few Slokams to be chanted. She actually sung them for us. Her experience with Mahaperiyava is in Youtube.
