1. Be open to Inspiration
2. Grasp with Imagination
3. Test with Intuition
The aim is to base assumptions on self-validating intuitions.
Whatever is - is obvious
(...When clarity has been attained; which typically takes right-motivation, effort and time.)
We can only rest on that which we spontaneously acknowledge - acknowledge from our real-true-divine self. During consciousness at its best and highest. That is intuition.
(The test of intuition is intuition: it is self-validating. The process may be repeated as often as subjectively required to check for foundational solidity.)
