Now saintly Barlaam, all but ready for to start, spake concerning his journey, and delivered Ioasaph his last lesson, saying, "Brother beloved, and dearest son, whom I have begotten through the Gospel, thou knowest of what King thou art the soldier, and with whom thou hast made thy covenant. This thou must keep steadfastly, and readily perform the duties of thy service, even as thou didst promise the Lord of all in the script of thy covenant, with the whole heavenly host present to attest it, and record the terms; which if thou keep, thou shalt be blessed. Esteem therefore nought in the present world above God and his blessings. For what terror of this life can be so terrible as the Gehenna of eternal fire, that burneth and yet hath no light, that punisheth and never ceaseth? And which of the goodly things of this world can give such gladness as that which the great God giveth to those that love him? Whose beauty is unspeakable, and power invincible, and glory everlasting; whose good things, prepared for his friends, exceed beyond comparison all that is seen; which eye hath not seen, nor ear heard, neither have entered into the heart of man: whereof mayest thou be shown an inheritor, preserved by the mighty hand of God!"

Here the king's son burst into tears of pain and vexation, unable to bear the parting from a loving father and excellent teacher. "And who," quoth he, "shall fill thy place, O my father? And whom like unto thee shall I find to be shepherd and guide of my soul's salvation? What consolation may I find in my loss of thee? Behold thou hast brought me, the wicked and rebellious servant, back to God, and set me in the place of son and heir! Thou hast sought me that was lost and astray on the mountain, a prey for every evil beast, and folded me amongst the sheep that had never wandered. Thou hast shown me the direct road to truth, bringing me out of darkness and the shadow of death, and, changing the course of my feet from the slippery, deadly, crooked and winding pathway, hast ministered to me great and marvellous blessings, whereof speech would fail to recount the exceeding excellence. Great be the gifts that thou receivest at God's hand, on account of me who am small! And may the Lord, who in the rewards of his gifts alone overpasseth them that love him, supply that which is lacking to my gratitude!"

Here Barlaam cut short his lamentation, and rose and stood up to pray, lifting up his either hand, and saying, "O God and Father of our Lord Jesu Christ, which didst illuminate the things that once were darkened, and bring this visible and invisible creation out of nothing, and didst turn again this thine handiwork, and sufferedst us not to walk after our foolishness, we give thanks to thee and to thy Wisdom and Might, our Lord Jesu Christ, by whom thou didst make the worlds, didst raise us from our fall, didst forgive us our trespasses, didst restore us from wandering, didst ransom us from captivity, didst quicken us from death by the precious blood of thy Son our Lord. Upon thee I call, and upon thine only begotten Son, and upon the Holy Ghost. Look upon this thy spiritual sheep that hath come to be a sacrifice unto thee through me thine unworthy servant, and do thou sanctify his soul with thy might and grace. Visit this vine, which was planted by thy Holy Spirit, and grant it to bear fruit, the fruit of righteousness. Strengthen him, and confirm in him thy covenant, and rescue him from the deceit of the devil. With the wisdom of thy good Spirit teach him to do thy will, and take not thy succour from him, but grant unto him, with me thine unprofitable servant, to become an inheritor of thine everlasting bliss, because thou art blessed and glorified for ever, Amen."

When that he had ended his prayer, he turned him round and embraced Ioasaph, now a son of his heavenly father, wishing him eternal peace and salvation, and he departed out of the palace, and went his way, rejoicing and giving thanks to God, who had well ordered his steps for good.

After Barlaam was gone forth, Ioasaph gave himself unto prayer and bitter tears, and said, "O God, haste thee to help me: O Lord, make speed to help me, because the poor hath committed himself unto thee; thou art the helper of the orphan. Look upon me, and have mercy upon me; thou who willest have all men to be saved and to come unto the knowledge of the truth, save me, and strengthen me, unworthy though I be, to walk the way of thy holy commandments, for I am weak and miserable, and not able to do the thing that is good. But thou art mighty to save me, who sustainest and holdest together all things visible and invisible. Suffer me not to walk after the evil will of the flesh, but teach me to do thy will, and preserve me unto thine eternal and blissful life. O Father, Son, and Holy Ghost, the consubstantial and undivided Godhead, I call upon thee and glorify thee. Thou art praised by all creation; thou art glorified by the intelligent powers of the Angels for ever and ever. Amen."

From that time forth he kept himself with all vigilance, seeking to attain purity of soul and body, and living in continency and prayers and intercessions all night long. In the day-time he was often interrupted by the company of his fellows, and at times by a visit from the king, or a call to the king's presence, but the night would then make good the shortcomings of the day, whilst he stood, in prayer and weeping until daybreak, calling upon God. Whence in him was fulfilled the saying of the prophet, "In nights raise your hands unto holy things; and bless ye the Lord."

But Zardan observed Ioasaph's way of life, and was full of sorrow, and his soul was pierced with grievous anxieties; and he knew not what to do. At the last, worn down with pain, he withdrew to his own home, feigning sickness. When this had come to the knowledge of the king he appointed in his place another of his trusty men to minister unto his son, while he himself, being concerned for Zardan's health, sent a physician of reputation, and took great pains that he should be healed.

The physician, seeing that Zardan was in favour with the king, attended him diligently, and, having right well judged his ease, soon made this report to the king; "I have been unable to discover any root of disease in the man: wherefore I suppose that this weakness is to be ascribed to distress of spirit." But, on hearing his words, the king suspected that his son had been wroth with Zardan, and that this slight had caused his retirement. So, wishing to search the matter, he sent Zardan word, saying "To-morrow I shall come to see thee, and judge of the malady that hath befallen thee."
