Namaste, This is a forwarded message regarding the works of Sri Shankaracharya. 

A list of all the works by Shri Adi Shankaracharya is given
below. Even today many scholars wonder how was it
possible for Acharya to write so much in a very short life
span of 32 years. It depicts that he was the greatest scholar
and a man on mission to teach & establish the
philosophy of Advaita Vedanta. Though majority of his
works concentrate on Advaita, he equally pitches on
bhakti since he believed that bhakti was a very essential
step for Chitta Shuddhi without which Self-realization was not
possible. Hence he composed verses and hymns in praise
of every lord, majority of which were concentrated on
Vishnu, Shiva and Shakthi. He wanted the people to worship
the lord in any form of their wish, the results of which must
finally purify their mind and make it fit for self realization.
From his life history it is evident that he was blessed
by Lord Narasimha, Goddess Saraswati and Lord
Vishvanatha. Hence one can find a true Vasihnava, Shaiva
and Shaakta in him. The most highlighting factor is the
baashya for Hastamalakeeyam written by Shri Shankaracharya since
rarely a Guru has written baashya for the work of his own
disciple. Below is the list of works by Shri Adi Shankaracharya which are
widely accepted to be his works.
