Who is Sri Ramana Maharshi?
The short story is that Ramana awakened to his true nature at age 16. He followed a mysterious longing to spend the rest of his life in silence by the Holy Mountain Arunachala. He did spend years in silence, but started teaching the path of Self-Inquiry when a growing number of devotees started hanging around. The rest is history, he moved down from the caves he had made his home, an Ashram was built in his honor, he left his body in 1950, but will always remain (as the answer of Self-Inquiry shows us).
