The first step in knowing is what we don’t know and wanting to know it. The boundaries of what we don’t know keep expanding, as we cover more and more ground by knowing. Then we realize how never-ending is knowing the external phenomenal world.
Then we try to figure out ‘how we know’. Mind comes across as enabling, but far more inhibiting. But we also realize that all objects, external or internal, are made of the same body-mind-soul architecture. Then we realize that the key to knowing the without is actually within.
We see as we are. Key is our ability to know the subtle, by being subtle. Then why go exploring outside when you can do the same by exploring the inside? With this comes realization that for ‘knowing anything, there’s need to know thyself’, and that is the only stepping stone to finally knowing thy “Self”.
