Four Principles of Reasoning
During Geshela's Sunday Teaching Q&A in response to a question on ignorance (ma rig pa) he cited the following principles of reasoning.
Four Principles of Reasoning (rigs pa bzhi) are: 1. the principle of causal efficiency 2. the principle of dependency 3. the principle of establishing a proof 4. the principle of nature The illustrative examples given by Geshela were: 1. Assembling and preparing food that turns out as a beautiful and delicious dish. 2. Relational principles, i.e., direction – north, south, east, and west. 3. Reasoning that brings one to establish conclusions, such as establishing impermanence, non-existence, and emptiness upon an examined basis of observation. 4. The principle of a natural process of reality itself, such as the very moment of (the mental continuum) going from a contaminated state to a non-contaminated state. The English translation I provided came from the below source, where you can find more about the subject!
