The Buddha contemplates dependent co-arising in reverse order just after his awakening.
Evaṁ me sutaṁ—ekaṁ samayaṁ bhagavā uruvelāyaṁ viharati najjā nerañjarāya tīre bodhirukkhamūle paṭhamābhisambuddho. Tena kho pana samayena bhagavā sattāhaṁ ekapallaṅkena nisinno hoti vimuttisukhapaṭisaṁvedī. Atha kho bhagavā tassa sattāhassa accayena tamhā samādhimhā vuṭṭhahitvā rattiyā majjhimaṁ yāmaṁ paṭiccasamuppādaṁ paṭilomaṁ sādhukaṁ manasākāsi:
Thus have I heard—At one time, the Blessed One was dwelling at |Uruvelā::name of a town in Magadha, lit. broad banks [uruvelā]| on the bank of the river Nerañjarā at the foot of a goatherd’s banyan tree, having just attained full awakening. Then, for seven days, the Blessed One sat in one posture experiencing the ease of liberation. At the end of those seven days, the Blessed One, emerging from that |perfect peace of mind::stability of mind, stillness of mind [samādhi]|, during the middle watch of the night, thoroughly paid attention to dependent co-arising in reverse order:
“Iti imasmiṁ asati idaṁ na hoti, imassa nirodhā idaṁ nirujjhati, yadidaṁ—avijjānirodhā saṅkhāranirodho, saṅkhāranirodhā viññāṇanirodho, viññāṇanirodhā nāmarūpanirodho, nāmarūpanirodhā saḷāyatananirodho, saḷāyatananirodhā phassanirodho, phassanirodhā vedanānirodho, vedanānirodhā taṇhānirodho, taṇhānirodhā upādānanirodho, upādānanirodhā bhavanirodho, bhavanirodhā jātinirodho, jātinirodhā jarāmaraṇaṁ sokaparidevadukkhadomanassupāyāsā nirujjhanti. Evametassa kevalassa dukkhakkhandhassa nirodho hotī”ti.
Thus, when this is not, that does not come to be; with the cessation of this, that ceases. That is - with the cessation of ignorance, formations cease; with the cessation of formations, consciousness ceases; with the cessation of consciousness, name-and-form cease; with the cessation of name-and-form, the six sense bases cease; with the cessation of the six sense bases, contact ceases; with the cessation of contact, feeling ceases; with the cessation of feeling, craving ceases; with the cessation of craving, clinging ceases; with the cessation of clinging, becoming ceases; with the cessation of becoming, birth ceases; with the cessation of birth, aging and death, sorrow, lamentation, suffering, displeasure, and despair cease. Thus, there is the cessation of this entire mass of suffering.
Atha kho bhagavā etamatthaṁ viditvā tāyaṁ velāyaṁ imaṁ udānaṁ udānesi:
Then, understanding the significance of this, the Blessed One at that time expressed this inspired utterance:
“Yadā have pātubhavanti dhammā,
Ātāpino jhāyato brāhmaṇassa;
Athassa kaṅkhā vapayanti sabbā,
Yato khayaṁ paccayānaṁ avedī”ti.
“When the nature of things becomes evident,
to the Brahmin meditating with continuous effort;
All his doubts are dispelled,
for he has known the ending of conditions.”
