According to Osho, 'dirt' is not inherently dirty; it is a judgment created by the dividing mind. Reality itself is undivided, beyond clean/dirty, good/bad. At the peak of awareness (paramahansa), such opposites dissolve. Yet do not imitate this by suppressing distinctions; cultivate awareness and let clarity ripen naturally. Then practical labels serve convenience, while your inner vision remains free of condemnation.
Things are not dirty or clean by themselves; our mind says so, and with growing awareness we can still use these labels without being trapped by them.
