大方便佛報恩經 3.3

3.3

爾時如來為母摩耶夫人并諸天眾說法九十日，閻浮提中亦九十日不知如來所在。大目揵連神力第一，盡其神力，於十方推求，亦復不知；阿那律陀天眼第一，遍觀十方三千大千世界，亦復不見；乃至五百大弟子，不見如來，心懷憂惱。優填大王戀慕如來，心懷愁毒，即以牛頭栴檀，摽像如來所有色身，禮事供養，如佛在時，無有異也。

At that time, the Tathāgata expounded the Dharma for ninety days for his mother, Lady Māyā, and the hosts of devas. In Jambudvīpa, for those ninety days they did not know where the Tathāgata was. Mahāmaudgalyāyana was foremost in supernatural powers, yet though he exhausted his supernatural powers searching in the ten directions, he too did not know; Aniruddha was foremost in the divine eye, yet though he gazed throughout the trichiliocosm of the ten directions, he too did not see him; and up to the five hundred great disciples, not seeing the Tathāgata, their minds harbored grief and distress. The great king Udayana longed for the Tathāgata, grief and sorrow piercing his heart, so he carved an image of all the marks of the Tathāgata's physical body using ox-head sandalwood, venerating, serving, and making offerings to it just as when the Buddha was present, without any difference.
