Primary Thinking (PT) is a reality difficult to grasp and recognize; so here is another aspect that may be of help in knowing when it is happening.
Another term for PT is 'direct-knowing' - and this is experienced as suddenly 'recalling' that we already-know something. So; a thought appears in the stream of mundane thinking that has a different quality; and that quality is somewhat like memory.
Thus we experience this thought as valid; as if we always knew it - but (as with direct-thinking) we have not reached this conclusion from evidence or reasoning. It is a direct and unmediated sharing, based on thinking the same thoughts as God (but, obviously, from a position of Much less capacity than God).
Suddenly we Just Know - and it feels like we always have known; but implicitly.
This is because spiritual thinking as it first emerges - before being 'translated' into language or some other symbolism - is true (at least, true within the limits of our capacity to comprehend).
It is true, because Primary Thinking is our (true) selves conscious participation in divine creation; and truth could briefly be defined as the reality of divine creation. It is that reality we know - know, because we are participating in it - with Primary Thinking.
