Tiryak

Depiction of the animal realm from a thangka of the Wheel of Life

tiryak (P. tiracchāna; T. dud 'gro དུད་འགྲོ་; C. chusheng), typically translated as "animals," are one of six classes of beings within our world-system, according to Buddhist cosmology.

Jamgon Kongtrul states:

Animals inhabit the sky, the water, and vast stretches of the earth. Their principal habitat, however, is the great ocean where animals such as nagas inhabit the depths, living [crowded together], like fermenting grains of beer.

Animals can co-exist with the gods (deva) or humans (manuṣya).
