Shankara, also called Shankaracharya, philosopher and theologian, most renowned exponent of the Advaita Vedanta school of philosophy, from whose doctrines the main currents of modern Indian thought are derived. He wrote commentaries on the Brahma-sutra, the principal Upanishads, and the Bhagavadgita, affirming his belief in one eternal unchanging reality (brahman) and the illusion of plurality and differentiation
Stotras by Shankaracharya
Out of His own volition, projecting power of His maya, Bramhan becomes Iswara, the personal God and to bless the devotees manifests Himself in several divine forms in which a seeker contemplates on Him. Hence Sri Shankara Bhagavat Pada purified the rituals of worship of Shiva, Devi, Vishnu, Surya, Ganapati and Kumara and composed devotional hymns on each of these divine forms to help the devotees.
