According to Osho, you don’t understand “a philosophy” here because it isn’t philosophy at all but living truth—a communion beyond mind. Trying to grasp it with thought guarantees misunderstanding; the mind is confused, drugged, and cannot comprehend no-mind. Words are only pointers—look to the moon, not the finger. Put mind aside, listen silently, and see directly; truth is being, not thinking or doing.
You can’t get it by thinking—quiet your busy mind and simply see/feel it directly.
