'A Treatise on Prosody'), also called the Pingala Sutras (Sanskrit: पिङ्गलसूत्राः, romanized: Piṅgalasūtrāḥ, lit. 'Pingala's Formulae'), is the foundational text of Chandas (prosody and metrics)—one of the six Vedāngas (auxiiiary science) of traditional Indian scholarship. The Chandaḥśāstra is a work of eight chapters written in the late Sūtra style, that relies on explanatory commentaries for full comprehension.
