What was it that experienced this ignorance?

It is very hard or very difficult to experienced ignorance. Following vipassana step could do. For me, not yet.

For my practice, as deep as I could feel was only moha (delusion). I feel like something cover my mind all the time. But someone told me that is anusaya (latent dispositions). Then who can tell ?

Anyway, it just the name. The wholesome point is I found something.

My opinion almost from my practice. This may different from the other and may more detail than tipitaka.
Some feeling I couldn't exactly compare to tipitaka. Just estimate that is ???.
Right or wrong, I didn't know but just share my experience for your more views.

The feeling inside could not show directly to the other. Could not compare directly to the other. Some feeling could not explain, especially explain to the person that never feel the same feeling. Some feeling didn't have a word to be explained.

To understand dhamma with thinking is good but with feeling is better. We still understand dhamma even some of our brain was destroyed.
