དེ་ནས་བཅོམ་ལྡན་འདས་ཀྱིས་རིགས་ཀྱི་བུ་དེ་དག་གི་བསམ་པ་ཐུགས་སུ་ཆུད་ནས། ཞལ་འཛུམ་པ་མཛད་དོ། །དེ་ནས་ཚེ་དང་ལྡན་པ་ཀུན་དགའ་བོ་སྟན་ལས་ལངས་ཏེ། བླ་གོས་ཕྲག་པ་གཅིག་ལ་གཟར་ནས།
The venerable Ānanda, rising from his seat, with his upper robe over one shoulder, rested his right knee on the ground and, placing his hands together in the gesture of homage toward the Blessed One, bowed toward the Blessed One and asked, “Blessed Lord, since the tathāgatas, arhats, perfectly complete buddhas do not smile without reason and circumstances, what is the reason and what are the circumstances for your smile?”
