According to Osho, 'all beings act according to their nature' means the qualities of nature move everyone—wise and ignorant alike—through birth, youth, illness, and death. Stubborn ego cannot alter this cosmic order. The difference is only in attitude: the ignorant resist and suffer; the wise witness, accept, and surrender, becoming instruments of the divine, letting what is natural happen without inner conflict.
Life runs on its own rules; you can’t stop it, but you can stop fighting, watch it, and flow with it.
