Swami Yogananda (Bengali: স্বামী যোগানন্দ, romanized: Sbāmī Yōgānanda) was a disciple of Ramakrishna Paramahansa, the 19th-century mystic.

He was also a dedicated and devoted attendant to Sarada Devi during her stay in Calcutta after Ramakrishna paramhangsha's death.

Navin Chandra was a poor descendant of the local aristocrat Sabarna Roy Choudhury family, who once owned the present metropolis of Kolkata and its adjoins.

Ramakrishna recognised the spiritual potentiality of Yogin and asked him to come more often, which impacted his studies and made his parents, who had high aspirations about him, concerned.

[5] After his marriage, Yogin met Ramakrishna again when the latter called him, and he once again began to frequent Dakshineswar to further his spiritual aspirations.

Once, when Yogin bought a faulty cooking pan from market by trusting the shopkeeper, he was severely reprimanded by his master.

This was a part of Ramakrishna's method to develop his disciples holistically, as he often said, "A man may aspire to be religious, but he need not be a fool.

"[7] Yogin also tested Ramakrishna in his own way as he was critical and analytical in nature, but every time he was proved wrong and these incidents finally established his unwavering faith on his master.

There he was initiated by her in Kalababu's Kunja, an ashrama established by Balaram Bose, a householder devotee of Ramakrishna, and thus he became the first disciple of Sarada Devi.

His health broke down with the severe strain of the austerities and spiritual practices, and he came back to Calcutta, to the newly formed Baranagar Math.

Yogananda was the first to organise the public celebration of Ramakrishna's birthday anniversary on a large scale in Dakshineswar temple premises.
