Ñamandú (the first; the origin and beginning) is the main god of Guaraní mythology. Defined as invisible, eternal, omnipresent and omnipotent. He is also known as Ñanderurusú, Ñanderuguasu ("Our Great Father") or Ñanderu pa-patenonde ("Our Great Last-First Father"). Ñamandu creates itself following the process of a vegetable. He first stands on his roots, spreads his branches, builds his crown and stands tall like a tree. Then his heart begins to glow. After eliminating the original darkness with the radiance of his heart, Ñamandú conceives the creative word (Ayvú) that will later be bequeathed to human beings to develop his language.
