アフラ・マズダー
Gaokerena is a large, sacred Haoma planted by Ahura Mazda. Ahriman (Ahreman, Angremainyu) created a frog to invade the tree and destroy it, aiming to prevent all trees from growing on the earth. As a reaction, Ahura Mazda created two kar fish staring at the frog to guard the tree. The two fish are always staring at the frog and stay ready to react to it. Because Ahriman is responsible for all evil including death, while Ahura Mazda is responsible for all good (including life).
