what needs to be understood

"One can only become a Sotāpanna, Sakadāgāmi, Anāgāmi, or Arahant through understanding the Four Noble Truths. #One must begin with Sotāpanna - there's no skipping stages. Not knowing the Four Noble Truths and the five aggregates is (Avijjā - ignorance). Wrongly perceiving beings, deities, or brahmas in the five aggregates is (Avijjā). From wrong perception comes: - Desire (Taṇhā) - Clinging (Upādāna) These three - Avijjā, Taṇhā, Upādāna - constitute the Truth of Origin (Samudaya-sacca). #Is Samudaya-sacca a being, city, country, sons, or daughters? No. #Understanding Samudaya-sacca is not a self but Path Truth (Magga-sacca). Where there are causes (Samudaya), don't the resultant aggregates arise? Is what arises beings or the five aggregates? Does anyone with aggregates escape aging, sickness, and death? This is Suffering Truth (Dukkha-sacca). #When Right View (Sammā-diṭṭhi) arises: - Wrong view ceases - Craving ends - Clinging stops - Kamma formation ceases - The three cycles of Dependent Origination break - #This is the Truth of Cessation (Nirodha-sacca) This is what needs to be understood..."
