I. I’ve searched the forum and haven’t found any explanation for this phrase yet, so it would be good if there is a detail explanation on this matter.
While reading the sutta, when encountering this sentence, I thought that this might be the key for the breakthrough:
“Susīma, first comes knowledge of the stability of natural principles. Afterwards there is knowledge of extinguishment.”
II. And furthermore, I wonder what is the relationship between the “knowledge of the stability of natural principles” and this practice of clear-seeing that the Buddha has taught Susima:
“So, Susīma, you should truly see any kind of form/feeling/perception/choices/consciousness at all—past, future, or present; internal or external; coarse or fine; inferior or superior; far or near: all form/feeling/perception/choices/consciousness—with right understanding: ‘This is not mine, I am not this, this is not my self.’"
III. I have practiced according to the above instruction for quite some times now, and through repeated reflection upon 5 subjects (5 clinging-aggregates) and their 11 attributes (past, future, …), I’m slowly understand somewhat about the Buddha’s teaching. But still not as clear as daylight, so I hope that I will receive details instruction on doing this kind of reflection too.
