Sri Ramakrishna’s spiritual endeavour was centred on ‘Mother’—the Divine Mother, whom he considered to be ‘all in all’ in his life. It is the Mother, who operated (Yantri) the machine (Yantra) named Sri Ramakrishna. His personality had two dimensions—one is ‘himself’ and another is ‘his Mother’. The Mother is the essence of his being, his mind and heart being completely immersed in Her. He had no other desire other than acting according to Mother’s will; he had no goal in his life other than what was shown to him by the Mother.
