His life was categorized by his fervent devotion to Mother Divine, Mahakali. Sri Kaleshwar says that Ramakrishna longed to see the Mother for many years. But none of the spiritual practices brought him to that experience. He had driven himself to the point of suicide because of the unfulfilled desire to see the Mother. Finally, a female saint initiated him into the practices of this lineage through which he was able to have the fulfillment of his deepest spiritual desire. He had a direct experience of the Mother after which he saw Her every day. The practices he used to see Mother Divine and realize Her are the practices that Sri Kaleshwar currently teaches in Penukonda. He says that a true spiritual path must give a direct experience of the divine. You must see what cannot be seen with your two eyes. This is the goal of the practices revealed by the Divine Lineage.
All religions lead to the same goal.
