On the day of the Satsangam, my mom had a very severe sore throat. We all thought that we were going to cancel the Satsangam. But, with all Mahaperiyava's grace and wonder, she was able to do the Satsangam without even coughing once.
In the beginning, she talked about Mahaperiyava's glory. She said that the Guru is not only the teacher importing their knowledge to students, but the actual Guru is the one who imports Gnana (wisdom) to the students. Then, she talked about Mahaperiyava's avataram. She told that Mahaperiyava's parents were thousand times more respectful because they have sacrificed a 13 year old boy to the world as a Sanyasi. Next, she quoted some of the unbelievable incidents such as how a small boy asked for Moksha (liberation) to Mahaperiyava and how Mahaperiyava even directed Siddha Purushas to focus on self realization. We can see Mahaperiyava's grace and glory in this video itself.
Here is the video below for Sri Mahaperiyava Divya Charithram. Enjoy!
