Q: Sir, I read somewhere that Sri Aurobindo took a holy lump of clay from the Panchavati of Dakshineswar (where Ramakrishna Paramahansa did his Mahatapas) and had in his Pondicherry room – is that just rumored or true?
ALOKDA: It is true. He had a great reverence for Sri Ramakrishna Paramhansa even though Sri Aurobindo’s own yoga went way further.
In many ways Sri Ramakrishna did prepare for the work that Sri Aurobindo undertook later by showing in his life and experience the essential unity of all religions. By doing so he arrived at the synthesis of different aspects of the Overmind experience. Sri Aurobindo went on to build the further synthesis between Matter and Spirit with the help of the Supermind.
Another important thread connecting them is the Kali aspect of the Divine Mother which played a very important role in the life of both.
