Mercedes De Acosta was asking Sri Ramana Maharshi about which religion, teacher, or guru she should follow that would be most helpful to her.
Bhagavan Ramana replied, “If they can help in the quest of the Self. But can they help? Can religion, which teaches you to look outside yourself, which promises a heaven and a reward outside yourself, can this help you? It is only by diving deep into the spiritual Heart that one can find the Self.”
Then Bhagavan placed his right hand on his right breast and continued, “Here lies the Heart, the dynamic, spiritual Heart. It is called Hridaya and is located on the right side of the chest and is clearly visible to the inner eye of an adept on the spiritual path. Through meditation you can learn to find the Self in the cave of this Heart.” (In Here Lies the Heart: By Mercedes De Acosta)
Bhagavan emphasizes the nature of the Heart and experience of the Heart a number of times in his teaching . Bhagavan says that the Mind is a power that arises from the Heart and this results in a feeling of being separate from the whole. When by investigation, the wise person examines the mind and traces its source via the clue of the sense of “I” back to the Heart, the mind gets resolved and Self is seen as the Heart.
