According to Swami Omkarananda's website:

Sri Swami Omkarananda Saraswati is a born Sage, Mystic and Genius. Already at the age of thirteen and fourteen his life was flooded with numerous spiritual experiences of the omnipresent and omniscient God. Under the dictates of these experiences, he left his home city in South India for the Himalayas, where the world-renowned Sage Sri Swami Sivananda recognised in him an embodiment of the high spirit of renunciation, profound divine wisdom, touching purity of heart, made him known as Bala Yogi, Bala Jnani, titled him as Adhyatma Kavita-Bhaskara and crowned him with Sannyasa-Diksha at the age of seventeen.
