Udanavarga 3.26-27

3.26

昔佛在摩竭提界善勝道場元吉樹下，德力降魔，坐自惟曰：「甘露法鼓聞於三千，昔父王遣五人，供養麻米執侍有勞，功報應敘。此五人者，在波羅奈國。」於是如來從樹下起，相好嚴儀明暉天地，威神震動，見者喜悅，至波羅奈國。未至中道，逢一梵志名曰憂呼，辭親離家求師學道，瞻覩尊妙驚喜交集。下在道側舉聲歎曰：「威靈感人儀雅挺特，本事何師乃得斯容？」

Formerly, when the Buddha was in the realm of Magadha, beneath the original auspicious tree at the supremely excellent bodhimaṇḍa, he subdued Māra through the power of his virtue. Sitting, he contemplated to himself: "The drum of the nectar-like Dharma shall be heard throughout the three-thousandfold [world]. Formerly, my father the king sent five men who made offerings of hemp and rice, and toiled in attending upon me; their service should be repaid. These five men are in the kingdom of Vārāṇasī." Thereupon, the Tathāgata arose from beneath the tree, his physical marks and dignified deportment illuminating heaven and earth, his awe-inspiring spiritual power shaking [the earth], so that those who saw him were filled with joy; and he proceeded to the kingdom of Vārāṇasī. Midway along the road before arriving, he met a brahmacārin named Youhu (Upaka), who had bidden farewell to his relatives and left home to seek a teacher and study the Way. Beholding the Bhagavān's wondrousness, he was struck with mixed alarm and joy. Standing aside by the road, he raised his voice in praise, saying, "Your spiritual majesty moves people; your deportment is elegant and preeminent. What master did you originally serve to attain such an appearance?"

In days of old Buddha was residing in Magadha, under the tree that overshadowed the Bodhimanda. Having by the power of his presence (virtue) overpowered Māra, he was considering with himself that the five men whom formerly his father had sent to look after him, and provide him with sufficient food, were in a condition to hear the sound of the drum of the Law of eternal life; and perceiving that they were at Benares, he immediately rose from underneath the tree, whilst the heaven and earth were lit up with a supernatural light, and the ground underneath him shook. Rejoiced at these indications, he went forward, and in the mid-road he encountered a Brahmachārin named Upaka (Yeon-fu), who had left his relations and home in search of a teacher to guide him in the way of truth. Beholding the World-honoured one, how reverend his appearance and joyous his mien as he went on the way, he cried to him with a loud voice, “O sir! full of religious thought and spiritual discernment, what is your history, and who has been your teacher, that you have arrived at such a condition as this?” To whom Buddha replied in the following stanzas :—

佛為憂呼而作頌曰：

The Buddha composed a hymn for Youhu, saying:
