Jai Sai Master!
Chivatam is a small village close to Tanuku, and there lived a lady by name Achhamma, who trasnformed in to an Avadhuta, and was later called as Chivatam Amma.
Once a person asked Amma, what is Tattvamasi. She immediately replied, burning of self. What SHE meant was when one loses the identify with I, then they get the realisation. This is exactly what Bhagavan Sri Ramana taught everyone who came to him.
Sri Chivatam Amma lived in the same way. She lived as a digambari (renounced clothing) all through HER life. She was known for her simplicity and lucidity while explaining. Surprisingly she had no formal education. This is one way of telling everyone, that to realise god, or the universal consciousness, one need not be a scholar. But pure in heart, compassionate and ever loving, and yearn for the realisation sincerely.
