Actually you are doing it right now. The development begins by hearing/reading the Dhamma and considering it. Questioning and discussing with the right people is also vital.
On another thread today I cited the translation of a Commentary by Bhikkhu Bodhi:
Mp explains the passage thus: “Nothing (lit., not all things) is worth holding to (sabbe dhammā nālaṃ abhinivesāya): here, ‘all things’ (sabbe dhammā) are the five aggregates, the twelve sense bases, and the eighteen elements. These are not worth holding to by way of craving and views. Why not? Because they do not exist in the way they are held to. They are held to be permanent, pleasurable, and self, but they turn out to be impermanent, suffering, and non-self.
What does it mean "**they do not exist in the way they are held to. They are held to be permanent, pleasurable, and self, **"?
Taking the twelve sense bases - the ayatanas- they are happening right now but it is assumed, for the one not steeped in the teachings of the SammasamBuddha, that “I see, I hear, my thinking” and so on . However, we learn that these are only conditioned phenomena that fall away instantly and so begins the understanding that “they turn > out to be impermanent, suffering, and non-self.”
Can I develop it even if I can’t see ultimate reality yet?
These seemingly profound and abstruse teachings can all be understood because it really is that way - it can be seen directly that thinking arises because it has to, that no one can stop seeing, or feeling, etc.
Many different ways are used to explain but it all points to the anattaness of phenomena. The development has its own pace, it depends on many factors. Even once there is some direct insight of ultimate realities it needs more pariyatti, more consideration of the teachings that further weld the intellectual to what was known directly.
So I praise you for taking on this journey. Which is because of your accumulations of wisdom and other parami, pubbekata punnata.
