According to Osho, “flowing with nature” can mean unconscious drift (like animals) or conscious harmony (like buddhas). Yielding to desire or sex as anesthesia regresses you; it is conformity without freedom. Meet natural energies with awareness; then the same forces refine into clarity and bliss, becoming a doorway upward rather than a descent into sleep.
Following nature wakes you only if you stay aware; mindless indulging in desire or sex puts you to sleep, while mindful presence turns it into growth.
