I have this pack of incense I bought in a store, and I have the same type, that Master Lin put a blessing in. I experience them as being different.
Judgement 'can' be involved, regarding talk of levels,,,, it is a choice(not a good one), or, one can 'discern' about something from a neutral perspective. Perhaps my conversation is colored by my preferences! I don't know...In theory though, minus the 'me' factor, levels are just places relative to other places. Everything is not on the same level, and that fact doesn't have to imply judgement. Good , better, and best , are different levels...
Also, understanding is a type of power. I think it is okay to talk about things, with the intention of reaching a higher 'level' of understanding.
Enough from me on this subject. ciao'
love,
