Swami Yogananda (Bengali: স্বামী যোগানন্দ, romanized: Sbāmī Yōgānanda) was a disciple of Ramakrishna, the 19th-century mystic. He took his formal initiation from Sarada Devi, the "holy mother" of Ramakrishna Order and spiritual consort of Ramakrishna. He was the first vice-president of Ramakrishna Mission. He belonged to the family of Sabarna Roy Choudhury, an aristocratic family of erstwhile Bengal. He had a very short life but he played a very important role during the formative years of Ramakrishna Mission. He was also a dedicated and devoted attendant to Sarada Devi during her stay in Calcutta after Ramakrishna's death. He was one of the disciples whom Ramakrishna referred to as "Iswarakoti" or the "ever perfect soul".
