Sri Ramakrishna Paramahansa (born on 18 February 1836 in Kamarpukur, West Bengal and died on August 16, 1886 in Calcutta), whose name was Gadadhar Chattopadhyay was a Bengali mystic whom many Hindus consider an avatara or divine incarnation. From 1856 he served as a priest of a temple of the goddess Kali and received instruction to achieve enlightenment. Ramakrishna had his first spiritual ecstasy at the age of six. For twelve years he practiced spiritual exercises under the guidance of teachers of the most diverse inspirations and religious orientations, including Christianity and Islam. Sri Ramakrishna also immersed himself in the disciplines of advaita vedanta, realizing the Absolute without form.
He affirmed that for each one of these ways he had attained enlightenment ( samadhi ), by which he affirmed that the followers of all religions could achieve the experience of the “Ultimate Reality”, if his surrender to God was intense enough. Ramakrishna Paramahansa was married to Sarada Devi . Sarada Devi was 5 years old and Ramakrishna 23. After the marriage, Sarada Devi stayed with her parents until she was 18 years old, when she met with Ramakrishna. After the marriage, Ramakrishna saw his wife again only when she was 14 years old and he gave her meditation techniques. When they finally met, Ramakrishna lived practically like a monk, so the marriage was never consummated.
For Ramakrishna, Sarada Devi was the Goddess and he praised her as such. Ramakrishna continued his work as a priest in the temple after his marriage. Eventually he was initiated into Tantrism by his teacher Bhairavi Brahmani. Ramakrishna learned the different sadhanas to control his mind. Then he tried the Vaisnava religion. Around 1864 he met the Vaisnava guru Jatadhari, who taught him the Vaishnava sadhanas. By then he visited the holy places of the district of Nadia, in Bengal, the same places where Chaytania and Nityananda were born. On that occasion he said that he had the vision of two children entering his body. Since then he said that he had developed devotion in the form of Kali’s son.
Then he formally started as a monk for Tota Puri, an itinerant monk who used to walk naked. For 11 months he learned the Vedvanta with him and later he was able to access Nirvikalpa Samadhi. Ramakrishna also tested the faith of Islam when he met the guru Govinda Roy in 1896, which in addition to Hinduism also practiced Sufism. During this time of his life, Ramakrishna dressed like a Muslim and said that after some time he had visions of the Prophet.
Finally, he tried Christianity when Shambu Charan Mallik read the Bible for him. After some time of practicing Christianity, Ramakrishna had a vision of Jesus and his mother. The fame of Ramakrishna transcended and he began to have disciples. Among them stood out their monastic disciples Swami Vivekananda and Swami Brahmananda, who later founded the Ramakrishna Mission.
