Silence and Grace are frequent topics that occur in devotee conversations with Bhagavan Sri Ramana. “Silence is most powerful” says Bhagavan in Day By Day, 9-3-46.
Bhagavan used to say that the highest spiritual teaching and transmission is given only in silence. True Silence comes when there is complete surrender to God without any reservation. There is no room for mental noise then and all is peace.
Here is an actual event narrated by T.K. Iyer where he witnessed the the power of Bhagavan’s silence.
