Arthur Osborne, a close devotee of Bhagavan Ramana said that while doing self-inquiry, he tried to focus on the spiritual Heart-center to the right of the chest. However, I have heard some scholars on Ramana’s teaching say that the Bhagavan did not recommend meditating on a specific location and that Arthur Osborne may have misunderstood the essential method and Bhagavan’s teaching. Is it necessary to meditate on the Spiritual Heart center in order to become Self-Realized? Some well known people like Nisaragadatta Maharaj and Krishnamurthi never mention the Heart in the same way that Bhagavan Ramana does. What is the explanation for this?
