As I come to know myself I see that I do not know myself, or even anything about myself or even anything at all. I see that all knowledge is illusory, all form is illusory. Any definition holds its own contradiction in its own existence. So knowing all I see that nothing is really known. Just knowing is. Ever new, appearing.
To see deeper than the human perspective, we have to venture outside of our human capacity. So very few are willing to die that death and thus those truths remain hidden.
