As with Lahiri Mahasaya and baba Hariharananda, Sanyal Mahasaya (1877-1962) was born in the district of Nadia, West Bengal. In despite of his determination to be a monk, he was destined to marry when he became 21, in this way he walked into the footsteps of his ideal and exemplary Gurudev Shri Lahiri Mahasaya. He had five children and still he is the youngest initiated Acharya (spiritual teacher) in the line of Kriya Yoga masters. He also was a talented and productive writer and wrote for example a comment on the Bhagavad Gita in Bengali, which showed his deep understanding of the scriptures and their relationship with Kriya Yoga.
Sanyal Mahasaya was respected as a totally realised yogi. Due to his talents and skills, his pure and spotless character and his inner spiritual wealth, he befriended with Rabindranath Tagore, the later Nobel prize winner. They worked together as teachers from 1902 till 1909. Together they founded the well-known Santiniketan institute where scientific and spiritual education are integrated.
