In the Maṇḍala system, the Rigveda is divided into ten Maṇḍalas. Each Maṇḍala contains a number of hymns (Sūktas), as detailed here-below, for a total of 1,028 hymns and about 10,600 verses for the whole Rigveda.

For each Maṇḍala, there are several Rishis (ṛṣi) as the ‘Mantra-draṣṭaras’ (the one having had the “vision” of the mantra); also, for every hymn, there is an invoked deity or Devatā, so there is a number of Devatās in every Maṇḍala. Some of the Rishis are listed here-below.
