Bhāradvājasutta
Ekaṁ samayaṁ āyasmā piṇḍolabhāradvājo kosambiyaṁ viharati ghositārāme. Atha kho rājā udeno yenāyasmā piṇḍolabhāradvājo tenupasaṅkami; upasaṅkamitvā āyasmatā piṇḍolabhāradvājena saddhiṁ sammodi. Sammodanīyaṁ kathaṁ sāraṇīyaṁ vītisāretvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho rājā udeno āyasmantaṁ piṇḍolabhāradvājaṁ etadavoca: “ko nu kho, bho bhāradvāja, hetu ko paccayo yenime daharā bhikkhū susū kāḷakesā bhadrena yobbanena samannāgatā paṭhamena vayasā anikīḷitāvino kāmesu yāvajīvaṁ paripuṇṇaṁ parisuddhaṁ brahmacariyaṁ caranti, addhānañca āpādentī”ti? “Vuttaṁ kho etaṁ, mahārāja, tena bhagavatā jānatā passatā arahatā sammāsambuddhena: ‘etha tumhe, bhikkhave, mātumattīsu mātucittaṁ upaṭṭhapetha, bhaginimattīsu bhaginicittaṁ upaṭṭhapetha, dhītumattīsu dhītucittaṁ upaṭṭhapethā’ti. Ayaṁ kho, mahārāja, hetu, ayaṁ paccayo yenime daharā bhikkhū susū kāḷakesā bhadrena yobbanena samannāgatā paṭhamena vayasā anikīḷitāvino kāmesu yāvajīvaṁ paripuṇṇaṁ parisuddhaṁ brahmacariyaṁ caranti, addhānañca āpādentī”ti.
With Bhāradvāja
At one time Venerable Bhāradvāja the Alms-Gatherer was staying near Kosambī in Ghosita’s monastery. Then King Udena went up to Bhāradvāja the Alms-Gatherer and exchanged greetings with him. When the greetings and polite conversation were over, he sat down to one side, and said to him: “Worthy Bhāradvāja, there are these young monks who are youthful, with pristine black hair, blessed with youth, in the prime of life; and they’ve never played around with sensual pleasures. What is the cause, what is the reason why they practice the full and pure spiritual life as long as they live, maintaining it for a long time?” “Great king, this has been stated by the Blessed One, who knows and sees, the perfected one, the fully awakened Buddha: ‘Please, monks, think of women your mother’s age as your mother. Think of women your sister’s age as your sister. And think of women your daughter’s age as your daughter.’ This is a cause, Great King, this is a reason why these young monks practice the full and pure spiritual life as long as they live, maintaining it for a long time.”
