Dasannaka Jātaka
Dasannaka Jātaka：Once the Bodhisatta was born as Senaka，a brahmin，counsellor to King Maddava of Benares．Maddava，seeing that his chaplain’s son was yearning for his chief queen，gave her to him for a week．But at the end of the week the queen ran away with the youth and the king became ill with longing for her．Senaka thereupon arranged for a festival，in the course of which the king was shown a man swallowing a sword．The king then asked his counsellors，Ayura，Pukkusa and Senaka，if anything could be harder to do than that．They，in turn，replied that to promise a gift，to make it，and having made it，not to regret it，these acts were，in increasing degrees，far harder than swallowing a sword made in Dasanna．The king，grasping the purport of their answers，regained his self-composure.
The story was told in reference to a monk who was tempted by his former wife.
The king was identified with the monk，Ayura with Moggallāna，and Pukkusa with Sāriputta （J.iii.336-41）.
