Mitre is the organizer of not only social, but also natural space. It is associated with waters, with the sun, it is the owner of wide pastures and the filler of waters, thanks to it it rains and plants grow.
Mitra accomplished several remarkable feats. One of them was committed annually and consisted of the capture and murder of a mighty bull, which was revived annually and personified the forces of evil.
Mitra was close to people in need and suffering, protected them during disasters, but demanded from them a pious life and strict adherence to moral law. For this he rewarded them with eternal bliss in the next world.
