A King celebrated in पुराणस् . He ruled over कुरुक्षेत्र . Once when there was a famine in the land, King मलयप्रभ exempted his subjects from all taxes. The greedy ministers did not like it and they advised him against it. The King yielded to the advice of his ministers. On one occasion मलयप्रभ 's son इन्दुप्रभ pleaded with his father and told him that he should not oppress his subjects at the instigation of his evil ministers. He added that the King was their "Kalpavṛkṣa" and the subjects were his "Kāmadhenus." But the King did not heed the advice of his son. He jokingly said that इन्दुप्रभ was also their "Kalpavṛkṣa". Stung by this taunt, इन्दुप्रभ took a solemn oath that he would either become a "Kalpavṛkṣa" or lay down his life in the attempt. He left the palace at once and began an austere तपस् . इन्द्र was pleased and appeared before him. Receiving his blessing, इन्दुप्रभ returned to his capital and stood there as a "Kalpavṛkṣa". He fulfilled the desires of the people. A few days later, इन्द्र came to the tree to test इन्दुप्रभ . He told इन्दुप्रभ : "Your mission of service is over; now you may come to Heaven". But he insisted that his subjects also should be taken with him to Heaven. इन्द्र was pleased at the devotion and love of इन्दुप्रभ for his subjects and agreed to take all his subjects also with him. इन्दुप्रभ gave up the form of the tree and resuming his own shape, accepted "Bodhisattvācārya".
