Question: Of the things you think you know a lot about, how much do you suppose you know about those things as compared to all that there is to know about them?
Answer: It depends on “how” I know them.
If I “know” what I know by my own mind, reason, logic; collecting, accumulating knowledge through my inherently egocentric and subjective perception, consciousness; then I can be certain that what I actually know is very little.
If I purposefully annul, empty my mind, reason, if I discard my egocentric, subjective logic and allow Nature’s “Upper Mind” to fill my emptied “database” instead; then I can be certain that this knowledge,”Natural Wisdom” is truthful since it is not mine, I just “borrowed it”.
