According to Osho, Tao cannot truly be defined; it is the supreme law (dharma, Rta) by which existence functions, knowable only by living it and dissolving into it, like a salt doll melting into the ocean. Words are mere pointers meant to kindle thirst; real understanding arises through direct experience, not conceptual descriptions.
You can’t explain Tao with words; it’s how everything works, and you only understand it by experiencing and becoming one with it—like salt disappearing in water.
