Nityananda (Bengali: শ্রী নিত্যানন্দ, Oriya: ନିତ୍ୟାନନ୍ଦ; b 1474 CE), was a Vaishnava saint, famous as a primary religious figure within the Gaudiya Vaishnava tradition of Bengal, is an expansion of Balarama. Nityananda was Chaitanya Mahaprabhu's friend and disciple. They are often mentioned together as Gaura-Nitai (Gaura, "golden one", referring to Chaitanya, Nitai being a shortened form of Nityananda) or Nimai-Nitai (Nimai being another name of Chaitanya). Followers often refer to Nityananda as 'Sri Nityananda', 'Prabhu Nityananda' or 'Nityananda Rama'.

According to Gaudiya-Vaishnava tradition Nityananda is an incarnation of Balarama, with Chaitanya Mahaprabhu being his eternal brother and friend, Krishna. He is considered the 'most merciful' incarnation of the Supreme Personality of Godhead.

Nityananda Prabhu was born to a religious Bandyaghati Brahmin, Mukunda Pandit (also known as Hadai Pandit) and Padmavati in Ekachakra (a small village in Birbhum district of present West Bengal) around the year 1474. His devotion and great talent for singing Vaishnava hymns (bhajan) were apparent from a very early age. He became well known in his youth for his dramatic re-enactments of Lord Rama's pastimes, wherein he would generally play the part of Lakshman, Rama's younger brother along with the other boys of Ekachakra.^{[citation needed]}

Bhagawan Nityananda (November/December, 1897 – August 8, 1961) was an Indian guru. His teachings are published in the "Chidakash Gita". Nityananda was born in Quilandy (Pandalayini), Kerala, South India.

Details about Nityananda's birth are relatively unknown. According to his disciples, Nityananda was found as an abandoned infant in Tuneri village, Kozhikode, India by a lady named Uniamma Nair, who was married to Chathu Nair. The Nair couple adopted this child and took care of him along with their own five children. Nityananda was named as Raman by his foster parents. The Nair couple were farmers,who also took care of the farms owned by a wealthy lawyer named Ishwar Iyer, who greatly trusted them. Nityananda's foster father died when he was three and his foster mother when he was six. Before dying she handed over her responsibility of Nityananda to Ishwar Iyer. Even in childhood, Nityananda seemed to be in an unusually advanced spiritual state, which gave rise to the belief that he was born enlightened. He was eventually given the name Nityananda, which means, "always in bliss".

Sri Nisargadatta Maharaj (April 17, 1897 – September 8, 1981), born Maruti Shivrampant Kambli, was an Indian spiritual teacher and philosopher of Advaita (Nondualism), and a Guru, belonging to the Inchgiri branch of the Navnath Sampradaya.

One of the 20th century's exponents of the school of Advaita Vedanta philosophy (nondualism), Sri Nisargadatta, with his direct and minimalistic explanation of non-dualism, is considered the most famous teacher of Advaita since Ramana Maharshi.

In 1973, the publication of his most famous and widely translated book, I Am That, an English translation of his talks in Marathi by Maurice Frydman, brought him worldwide recognition and followers.

Sri Nisargadatta was born on April 17, 1897, at break of dawn, the full moon in the month of Chaitra, to a devout Hindu couple Shivrampant Kambli and Parvatibai, in Bombay. The day was also the birthday of Lord Hanuman, hence the boy was named 'Maruti', after Lord Hanuman himself. Maruti Shivrampant Kambli was brought up in Kandalgaon, a small village in the Ratnagiri district of Maharashtra, where he grew up amidst his family of six siblings, two brothers and four sisters, and deeply religious parents. His father, Shivrampant, worked as a domestic servant in Mumbai and later became a petty farmer in Kandalgaon.
