According to Osho, ulatbansi means speaking from the inverted vision born of samadhi, where the doer dissolves, effects become causes, and means become ends; like the flute playing the player. Kabir casts words into such paradox to convey the saint’s headstand view, overturning ordinary values and logic so seekers glimpse egoless absorption and the world seen from within, not outside.
He’s saying saints talk in upside-down ways—like ‘the flute plays the musician’—because in deep meditation everything flips and the ego isn’t in charge.
