HI Green,
Buddhism isn’t philosophical nihilism.
In SN 35.15, SN 35.16 Buddha states that wisdom is critical to Awakening.
“Mendicants, I went in search of the eye’s gratification, “Cakkhussāhaṁ, bhikkhave, assādapariyesanaṁ acariṁ. and I found it. Yo cakkhussa assādo tadajjhagamaṁ. I’ve seen clearly with wisdom the full extent of the eye’s gratification. Yāvatā cakkhussa assādo paññāya me so sudiṭṭho.
I went in search of the eye’s drawback, Cakkhussāhaṁ, bhikkhave, ādīnavapariyesanaṁ acariṁ. and I found it. Yo cakkhussa ādīnavo tadajjhagamaṁ. I’ve seen clearly with wisdom the full extent of the eye’s drawback. Yāvatā cakkhussa ādīnavo paññāya me so sudiṭṭho.
I went in search of escape from the eye, Cakkhussāhaṁ, bhikkhave, nissaraṇapariyesanaṁ acariṁ. and I found it. Yaṁ cakkhussa nissaraṇaṁ tadajjhagamaṁ. I’ve seen clearly with wisdom the full extent of escape from the eye. Yāvatā cakkhussa nissaraṇaṁ, paññāya me taṁ sudiṭṭhaṁ.
Knowledge and vision arose in me: Ñāṇañca pana me dassanaṁ udapādi: ‘My freedom is unshakable; this is my last rebirth; now there’ll be no more future lives.’” ‘akuppā me vimutti, ayamantimā jāti, natthi dāni punabbhavo’”ti.
In SN 35.18 and SN 35.18 Buddha states that there is gratification, wretchedness and escape from the senses, because if there were not people wouldn’t become aroused, disillusioned and find escape.
“Mendicants, if there were no gratification in the eye, sentient beings wouldn’t be aroused by it. “No cedaṁ, bhikkhave, cakkhussa assādo abhavissa, nayidaṁ sattā cakkhusmiṁ sārajjeyyuṁ. But since there is gratification in the eye, sentient beings are aroused by it. Yasmā ca kho, bhikkhave, atthi cakkhussa assādo tasmā sattā cakkhusmiṁ sārajjanti.
If the eye had no drawback, sentient beings wouldn’t grow disillusioned with it. No cedaṁ, bhikkhave, cakkhussa ādīnavo abhavissa, nayidaṁ sattā cakkhusmiṁ nibbindeyyuṁ. But since the eye has a drawback, sentient beings do grow disillusioned with it. Yasmā ca kho, bhikkhave, atthi cakkhussa ādīnavo tasmā sattā cakkhusmiṁ nibbindanti.
If there were no escape from the eye, sentient beings wouldn’t escape from it. No cedaṁ, bhikkhave, cakkhussa nissaraṇaṁ abhavissa, nayidaṁ sattā cakkhusmā nissareyyuṁ. But since there is an escape from the eye, sentient beings do escape from it. Yasmā ca kho, bhikkhave, atthi cakkhussa nissaraṇaṁ tasmā sattā cakkhusmā nissaranti.
In SN 35.25 Buddha teaches the method for giving up the all by “direct knowledge and complete understanding”
“Mendicants, I will teach you the principle for giving up the all by direct knowledge and complete understanding. “Sabbaṁ abhiññā pariññā pahānāya vo, bhikkhave, dhammaṁ desessāmi. Listen … Taṁ suṇātha.
And what is the principle for giving up the all by direct knowledge and complete understanding? Katamo ca, bhikkhave, sabbaṁ abhiññā pariññā pahānāya dhammo?
The eye should be given up by direct knowledge and complete understanding. Sights should be given up by direct knowledge and complete understanding. Eye consciousness should be given up by direct knowledge and complete understanding. Eye contact should be given up by direct knowledge and complete understanding. The painful, pleasant, or neutral feeling that arises conditioned by eye contact should be given up by direct knowledge and complete understanding. Cakkhuṁ, bhikkhave, abhiññā pariññā pahātabbaṁ, rūpā abhiññā pariññā pahātabbā, cakkhuviññāṇaṁ abhiññā pariññā pahātabbaṁ, cakkhusamphasso abhiññā pariññā pahātabbo, yampidaṁ cakkhusamphassapaccayā uppajjati vedayitaṁ sukhaṁ vā dukkhaṁ vā adukkhamasukhaṁ vā tampi abhiññā pariññā pahātabbaṁ …pe…
In SN 35. 27 he states without directly knowing and completely understanding the all, without dispassion for it and giving it up, you can’t end suffering
“Mendicants, without directly knowing and completely understanding the all, without dispassion for it and giving it up, you can’t end suffering. “Sabbaṁ, bhikkhave, anabhijānaṁ aparijānaṁ avirājayaṁ appajahaṁ abhabbo dukkhakkhayāya.
And what is the all, without directly knowing and completely understanding which, without dispassion for it and giving it up, you can’t end suffering? Kiñca, bhikkhave, sabbaṁ anabhijānaṁ aparijānaṁ avirājayaṁ appajahaṁ abhabbo dukkhakkhayāya?
The eye, sights, eye consciousness, and things knowable by eye consciousness. Yañca, bhikkhave, cakkhu, ye ca rūpā, yañca cakkhuviññāṇaṁ, ye ca cakkhuviññāṇaviññātabbā dhammā …pe…
