[exhibeKed]

There are "Yatana 16" in Visuddhimagga which I use for check back my practice. But only some step I found. Some could not because each one each experience.
The adventage is this make me sure the way I practice.
For example. The first step "Nama rupa pariccheda yatana (I don't know exactly pali - this pali from Thai pronounce)", I found that this is close to the separation of observer and object.
