Upadesasahasri (Upadeśasāhasri, English: A thousand (verses of) teachings) is a work (Prakaraṇa grantha) of Adi Shankara. This work is considered as Shankara's most important non-commentarial work.
Upadesasahasri is divided into two parts – one is verse and another is prose. There are nineteen chapters (prakarana) in the verse (or Metrical Part (Padyabandha). The manuscript of this work indicates that the two parts (prose and verse) were regarded as independent works and studied or commented upon separately. Manuscript also suggests the possibility that any single chapter could be studied differently – apart from the rest. This means one could/can start reading this work anywhere.
