Khidr, n.All

Khidr (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the Verdant One, the tireless immortal wanderer born where the dead fish leapt back into the sea — the son of the watery deep who teaches Moses wisdom he cannot endure.

Khidr (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the messenger of Allah in the Koran who at first frightens Moses with his misdeeds; the legend sets out Moses' relation to his shadow, his servant Joshua, and to the self, Khidr.

Khidr (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a symbol of the self — born in a cave, endlessly self-renewing, a wisdom whose acts transcend reason: scuttling a ship, killing a youth, raising a wall for no payment.
