After Ramkrishna his achievement of all the "Bhavas", he concentrated in attaining "Savikalpa Samadhi" which is depicted as the vision and union with Lord Krishna. The mud hut in the Panchavati where Ramakrishna performed his "Advaitic Sadhana" was replaced by brick one. During this time Ramakrishna devoted himself in Sanyasa by a Vedantic ascetic, Totapuri who was a wandering monk. Totapuri was named as "Nangta"or "Langta"( naked one) by Ramakrishna. As described by Ramakrishna, Totapuri was "a teacher of masculine strength, a sterner mien, a gnarled physique, and a virile voice." Totapuri as a believer of formless Brahman, considered the world as illusory and the worship of Gods and Goddesses as fantasies of the deluded mind.
Ramakrishna, firstly guided by the rites of Sanyasa(renunciation of all ties to the world) by Totapuri, was led to the knowledge of "Advaita" which depicts that "Brahman alone is real and the world is illusory; I have no separate existence ; I am that Brahman alone." Ramakrishna, Under the guidance of Totapuri , experienced "Nirvikalpa Samadhi" which is considered to be the highest form of spiritual consciousness. Being in the company of Ramakrishna, Totapuri ushered him in the teaching of "advaita" for nearly eleven months. Inspired by his guru, Ramakrishna surpassed dualism and annihilated the idea of Maa Kali from his consciousness. Ramakrishna, for six months, was in a state of deep contemplation after the departure of Totapuri. A command from Maa Kali provoked Ramakrishna to end his "Nirvikalpa Samadhi": "Remain in Bhavamukha; for the enlightenment of the people, remain in Bhavamukha", which is referred to as a state between "samadhi "and absolute consciousness.
