Chandra Shakha Nyaya. This is an ancient technique and analogy in Sanskrit which teaches one to locate the moon in the sky.
How would you teach it, if the crescent moon was just a sliver, and practically not discernible? The sky is vast and has no other reference points. In the early evening, the sun’s light might be quite bright as well, further reducing the chances of spotting the baby crescent.
The answer is, via CSN, or “moon-branch technique”. The teacher would point to a nearby tree, and then to a trunk on the tree, then to a branch on the tree, then the tip of the branch, and finally the eye would spot the moon, as if just off the tip of the branch.
The moon is completely separate from the tree, trunk and branch. Very similar to how the soul or Atman within us is completely separate from the body, mind and intellect. Yet we must use these very faculties (whether through meditation, reading the scriptures or living a dharmic life) and go beyond.
