According to Jain cosmology, in the three "Aras" (unequal periods) of the descending arc (Avasarpini), Kalpavrikshas provided all that was needed, but towards the end of the third "ara", the yield from them diminished. Eight types of these trees are described in some texts, each of which provided different objects. Thus from the "Madyanga tree" delicious and nutritious drinks could be obtained; from the "Bhojananga", delicious food; from "yotiranga", light more radiant than the sun and the moon; while from "Dopanga" came indoor light. Other trees provided homes, musical devices, table ware, fine garments, wreaths and scents.
