Yogatrayananda was a remarkable scholar saint (1848 - 1927). He was born Sashi Bhushan Sanyal in Bali, Howah, and was initiated at the age of 10 by Swami Shivramananda. After his guru passed away, he took the name of Shivramkinkar (server of Shivram). He was given the title of Yogatrayananda, because of his excellence in all the three Yoga paths.
He is the author of the classic 'arya shAstra pradip' (Light of the Aryan scriptures), of mAnabtattva (Principles of Humanity) and Paraloktattva (Principles of the afterlife).
He lived in Baranagar and visited Shri Ramakrishna in his youth. The young Vivekananda and Abhedananda used to go to him to study the scriptures.Yogatrayananda later moved to Varanasi and then returned to Bengal.
Dr. Gopinath Kaviraj wrote about him in his memoirs of saints, about the great influence of his teaching in his development. He is referenced by Alain Dinielou in the book 'Myths and Gods of India'. There is a brief reference to him in the article "Conversations with Swami Nirgunanada" to the question 'What is surrender?' (In Bengal there was a great scholar named Shashi Bhusan Sanyal who was contemporary of the then great saint of India Sri Ramakrishna.)
