As soon as anyone thinks "undivided" or "divided" s/he's already made a mistake. The task of a sage is to keep pulling the rug out from under people until it is realized that there is no solid ground to stand on. When it is finally realized that there is no solid ground to stand on, then where is one standing? For folks who travel this path far enough there is a simple concrete answer to this question. It is the difference between being guest or host.
Once upon a time a young seeker visited a famous sage.
The seeker said, "I've come for instruction."
The sage asked, "Where did you come from?"
The seeker responded, "I've come from (a particular) southern province."
The sage replied, "You ricebag! How could you possibly have come from a southern province?"
This exchange reportedly opened the seeker's eyes.
