Darśana, is from the Sanskrit root: dṛś, literally, ‘To See’.
‘Seeing’ in its analytic meaning is is all about catching the beam in your own eye. I catch the beam in my eye: and catch myself catching myself; and catch myself catching myself catching myself. And so on.
I See. I See that I See. I See that I See that I See…
I Know. I Know that I Know. I Know that I Know that I Know…
Darśana is the ‘Backward Step’, an Infinite Regress back to True Nothing pursued without blinking or winking. It is formalized as the Self-Eating Expression [SEE’].
The Sanskritic analogue of the Greek Phílosophía [‘Lover of Wisdom’] is the Seer: ‘One who See’s’. One loves Wisdom of course, but it is not settled until one ‘Sees’. Argument is docked on assumption. One can question it; reroute the inference; toss-up diversionary flak. But you can’t ‘unsee’ what you see.
There are levels and levels of ‘Seeing’. For a pious Hindu, to see the adorned deity with a full and sincere heart is in turn to be seen by the deity in an act of divine grace [and often, such simple piety trumps all philosophy and metaphysics].
Watch out, though. Sanskrit Literature carries a long list of exclusive sightings made over the centuries by God-Men and Knaves. Each is raised up the flagpole and if anyone salutes a new school is born. All orthodox schools are officially Darśanas.
