Anattalakkhana Sutta
The Anattalakkhaṇa Sutta (Pali) or Anātmalakṣaṇa Sūtra (Sanskrit), is traditionally recorded as the second discourse delivered by Gautama Buddha. The title translates to the "Not-Self Characteristic Discourse", but is also known as the Pañcavaggiya Sutta (Pali) or Pañcavargīya Sūtra (Skt.), meaning the "Group of Five" Discourse.
