What is "shivananda"

Swami Shivananda (1854–1934), born Tarak Nath Ghosal, was a Hindu spiritual leader and a direct disciple of Ramakrishna, who became the second president of the Ramakrishna Mission. His devotees refer to him as Mahapurush Maharaj (Great Soul). Shivananda and Subodhananda were the only direct disciples of Ramakrishna to be filmed. He was a Brahmajnani ("knower of Brahman or the Supreme Being"). Shivananda introduced the celebration of the birthdays of his brother-monks. He was known to have laid the foundation stone of Shri Ramakrishna Temple at Belur Math, which was designed by Swami Vijnanananda.
