Three types of investigation
The three types of investigation refer to the process of determining the validity of a scripture[1]
- the demonstration of what is evident (mngon gyur) is not invalidated by direct perception (mngon sum),
- the demonstration of what is hidden (lkog gyur) is not invalidated by inference (rjes dpag),
- the demonstration of what is extremely hidden (shin tu lkog gyur) is not contradicted (internally) by previous or later statements.
from Mipham Rinpoche, Words That Delight, 347.
