Stories tell that young Adi Shankaracharya showed a great intelligence and talent as a child, and even wanted to live as a hermit already. Some sources state that he left home to search for his guru at the age of eight and started to write commentaries on the Vedic texts when he was 16. One of his most famous works, and one of the most important texts of the Vedanta school of Hinduism, is the commentary on the "Brahma Sutras," titled the "Brahmasutrabhasya."
Adi Shankaracharya is considered a jnana yogi, raja yogi and bhakti yogi. He taught that knowledge is the right path in attaining spiritual liberation, but he also taught Raja yoga, revealing the secrets of pranayama, mantra, meditation, concentration and the chakras. He composed several chants to various Hindu deities. Some sources state that he rejected yoga, but, in fact, he just did not agree with the dualistic principle of purusha and prakriti and declared a supreme reality instead.
