That is exactly right. Glad you understood. It is a step-by-step process to get to the Arahanthood.
– Most people cannot even imagine how the perception of “me” can go away. So, that is the wrong starting point.
– One first needs to get the “correct view” at the Sotapanna stage. That “correct world view” is confirmed at the Sotapnna phala moment. Every effort needs to be made to understand the Four Noble Truths/Paticca Samuppada/Tilakkhana to get to that stage. it is not that the world does not offer “pleasurable things.” But the problem is that if one attaches to them, that WILL lead to future suffering. It is hard to see that because most of that suffering comes in future lives!
– Then, to get rid of the saññā vipallasa at the Anagami stage and to get rid of the even deeper citta vipallasa at the Arahant stage, one must contemplate that “correct world view” of anicca, dukkha, anatta repeatedly, especially when one is “drawn back” to sensory pleasures.
