Sri Thakur Gadadhar Chattopadhyaya Ramakrishna Paramahamsa (February 18, 1836 - August 16, 1886) was a Bengali saint. A devotee of the mother goddess Kali and a teacher of Advaita Vedanta Hinduism, he preached that "all religions lead to the same goal." He placed "spiritual religion" above "blind ritualism."
When Gadadhar started worshipping the deity Bhavatarini, he began to question if he was worshipping a piece of stone or a living Goddess. If he was worshipping a living Goddess, why should she not respond to his worship? This question nagged him day and night. Then, he began to pray to Kali: "Mother, you've been gracious to many devotees in the past and have revealed yourself to them. Why would you not reveal yourself to me, also? Am I not also your son?"
