"One must know the Four Noble Truths to become a Sotāpanna, Sakadāgāmi, Anāgāmi, and Arahant. Without knowing the Four Noble Truths, can one become a Sotāpanna? Without becoming a Sotāpanna, can one become an Arahant? #One_must_start_with_Sotāpanna. Isn't this worth examining?
Not knowing the Four Noble Truths is (avijjā, ignorance). Not knowing the Five Aggregates is (avijjā). Wrongly perceiving the Five Aggregates as humans, devas, or brahmas is (avijjā).
Wrong perception is avijjā. With wrong perception, what arises? (taṇhā, craving). Clinging to what we can't let go of is (upādāna, attachment). When these three - avijjā, taṇhā, upādāna are grouped in terms of Truth, which Truth is it? (Samudaya Sacca, Truth of Origin).
#Is_Samudaya_Sacca human? Deva? Brahma? Children? How clear is this? Is it the self that knows Samudaya Sacca, or is it Magga Sacca (Path Truth) that knows it? It's Magga Sacca that knows. Isn't this worth examining?
#When_there_is_Samudaya_as_cause, don't the resultant aggregates arise? What appears - humans, devas, brahmas, or the Five Aggregates? How clear is this! Do those who get aggregates escape aging, sickness, and death? Which Truth is this? (Dukkha Sacca, Truth of Suffering). Doesn't the Buddha teach Samudaya and Dukkha? This is Dukkha arising from Samudaya.
Isn't it necessary to know Samudaya Sacca? Dukkha Sacca? Magga Sacca? Nirodha Sacca? One can only eliminate what one knows. #One_must_know_them_as_aggregates. When one clearly and precisely knows the Five Aggregates, the wrong views of self as human, deva, or brahma fall away.
Continue examining these aggregates - whether rūpakkhandha, vedanākkhandha, saññākkhandha, saṅkhārakkhandha, or viññāṇakkhandha - are they permanent or impermanent? When one truly knows they are impermanent, does taṇhā still come? Does upādāna still come? Don't the āsavas of kāmāsava and bhavāsava cease?
When knowing the Five Aggregates, don't diṭṭhāsava and avijjāsava cease? Don't all four āsavas end? When they end, doesn't Samudaya Sacca die? Don't the aggregates' cycle end? Isn't this what's called Nirodha Sacca..."
