Gaurakisora Dasa Babaji
Gaurakisora Dasa Babaji (; 1838–1915) is a well-known acharya from the Gaudiya Vaishnava tradition of Hinduism, and is regarded as a "Mahatma" or saint by followers of his lineage. During his lifetime Gaurakisora Dasa Babaji became famous for his teachings on the process of Bhakti Yoga and for his unorthodox "avadhuta" like behaviour as a sadhu, or babaji in Vrindavan. He was born on 17 November 1838 in a simple mercantile family in the village of Vagyana, near to Tepakhola in the district of Faridpur, part of modern-day Bangladesh. After the death of his wife when  he was twenty nine years old, he accepted the life of a Babaji in the Gaudiya Vaishnava tradition under the tutelage of Jagannatha Dasa Babaji, after meeting the latter's disciple, Bhagavat Dasa Babaji. He became a mendicant, staying in the holy cities of Vrindavan and Navadwip, deeply absorbed in singing and chanting the sacred names of Radha and Krishna (Bhajan). In the early 1900s, Bhaktisiddhanta Sarasvati Thakura acknowledged that he took initiation (in a night dream) from Gaurakisora Dasa Babaji and given the name 'Varsabhanavi devi daitya dasa'. Bhaktisiddhanta Sarasvata would later take an unorthodox form of initiation into  the sannyasa order, in which "he simply sat down before a picture of Gaura Kisora dasa Babaji and invested that order upon himself." This is considered by some a contested topic.
