Adi Shankara, a Hindu philosopher of the Advaita Vedanta school, wrote many works in his life-time of thirty two years; however, many works thought to be of his authorship are debated and questioned as to their authorship today. His works deal with logically establishing the doctrine of Advaita Vedanta as he saw it in the Upanishads. He formulates the doctrine of Advaita Vedanta by validating his arguments on the basis of quotations from the Vedas and other Hindu scriptures. He gives a high priority to svānubhava (personal experience) of the student. Also, a large portion of his works is polemical in nature. He directs his polemics mostly against the Sankhya, Bauddha, Jaina, Vaisheshika and other non-vedantic Hindu philosophies.
Traditionally, his works are classified under (commentary), (philosophical treatise) and Stotra (devotional hymn). The commentaries serve to provide a consistent interpretation of the scriptural texts from the perspective of Advaita Vedanta. The philosophical treatises provide various methodologies to the student to understand the doctrine. The devotional hymns are rich in poetry and piety, serving to highlight the helplessness of the devotee and the glory of the deity. A partial list of his works is given below.
