Aṅguttara NikāyaBook of the Twos2.46. Bombast
“Monks, there are these two assemblies. Which two? The assembly trained in bombast and not in cross-questioning, and the assembly trained in cross-questioning and not in bombast.
“And which is the assembly trained in bombast and not in cross-questioning?
“There is the case where in any assembly when the discourses of the Tathagata—deep, deep in their meaning, transcendent, connected with emptiness—are recited, the monks don’t listen, don’t lend ear, don’t set their hearts on knowing them; don’t regard them as worth grasping or mastering. But when discourses that are literary works—the works of poets, artful in sound, artful in expression, the work of outsiders, words of disciples—are recited, they listen, they lend ear, they set their hearts on knowing them; they regard them as worth grasping & mastering. Yet when they have mastered that Dhamma, they don’t cross-question one another about it, don’t dissect: ‘How is this? What is the meaning of this?’ They don’t make open what isn’t open, don’t make plain what isn’t plain, don’t dispel doubt on its various doubtful points. This is called an assembly trained in bombast, not in cross-questioning.
“And which is the assembly trained in cross-questioning and not in bombast?
“There is the case where in any assembly when discourses that are literary works—the works of poets, artful in sound, artful in rhetoric, the work of outsiders, words of disciples—are recited, the monks don’t listen, don’t lend ear, don’t set their hearts on knowing them; don’t regard them as worth grasping or mastering. But when the discourses of the Tathagata—deep, deep in their meaning, transcendent, connected with emptiness—are recited, they listen, they lend ear, they set their hearts on knowing them; they regard them as worth grasping & mastering. And when they have mastered that Dhamma, they cross-question one another about it and dissect it: ‘How is this? What is the meaning of this?’ They make open what isn’t open, make plain what isn’t plain, dispel doubt on its various doubtful points. This is called an assembly trained in cross-questioning and not in bombast.”
Staying at Savatthi. "Monks, there once was a time when the Dasarahas had a large drum called 'Summoner.' Whenever Summoner was split, the Dasarahas inserted another peg in it, until the time came when Summoner's original wooden body had disappeared and only a conglomeration of pegs remained. [1]
"In the same way, in the course of the future there will be monks who won't listen when discourses that are words of the Tathagata — deep, deep in their meaning, transcendent, connected with emptiness — are being recited. They won't lend ear, won't set their hearts on knowing them, won't regard these teachings as worth grasping or mastering. But they will listen when discourses that are literary works — the works of poets, elegant in sound, elegant in rhetoric, the work of outsiders, words of disciples — are recited. They will lend ear and set their hearts on knowing them. They will regard these teachings as worth grasping & mastering.
"In this way the disappearance of the discourses that are words of the Tathagata — deep, deep in their meaning, transcendent, connected with emptiness — will come about.
"Thus you should train yourselves: 'We will listen when discourses that are words of the Tathagata — deep, deep in their meaning, transcendent, connected with emptiness — are being recited. We will lend ear, will set our hearts on knowing them, will regard these teachings as worth grasping & mastering.' That's how you should train yourselves."
