Sīsapāvanasutta
Ekaṁ samayaṁ bhagavā kosambiyaṁ viharati sīsapāvane. Atha kho bhagavā parittāni sīsapāpaṇṇāni pāṇinā gahetvā bhikkhū āmantesi: “Taṁ kiṁ maññatha, bhikkhave, katamaṁ nu kho bahutaraṁ— yāni vā mayā parittāni sīsapāpaṇṇāni pāṇinā gahitāni yadidaṁ upari sīsapāvane”ti? “Appamattakāni, bhante, bhagavatā parittāni sīsapāpaṇṇāni pāṇinā gahitāni; atha kho etāneva bahutarāni yadidaṁ upari sīsapāvane”ti. “Evameva kho, bhikkhave, etadeva bahutaraṁ yaṁ vo mayā abhiññāya anakkhātaṁ. Kasmā cetaṁ, bhikkhave, mayā anakkhātaṁ? Na hetaṁ, bhikkhave, atthasaṁhitaṁ nādibrahmacariyakaṁ na nibbidāya na virāgāya na nirodhāya na upasamāya na abhiññāya na sambodhāya na nibbānāya saṁvattati; tasmā taṁ mayā anakkhātaṁ.
In a Rosewood Forest
At one time the Buddha was staying near Kosambī in a rosewood grove. Then the Buddha picked up a few rosewood leaves in his hand and addressed the mendicants: “What do you think, mendicants? Which is more: the few leaves in my hand, or those in the grove above?” “Sir, the few leaves in your hand are a tiny amount. There are far more leaves in the grove above.” “In the same way, there is much more that I have directly known but have not explained to you. What I have explained is a tiny amount. And why haven’t I explained it? Because it’s not beneficial or relevant to the fundamentals of the spiritual life. It doesn’t lead to disillusionment, dispassion, cessation, peace, insight, awakening, and extinguishment. That’s why I haven’t explained it.
