According to Osho, speculating about mankind’s future is futile—'humanity' is an abstraction and tomorrow never arrives. Liberation from war and injustice begins only with individual transformation here and now: drop inner conflict, violence and fear; cultivate love, meditation, celebration. Become a living example without missionary zeal; your fragrance may inspire others, but deciding for the whole is neither possible nor necessary.
Don’t worry about fixing everyone—be peaceful and loving yourself right now, and others may catch the vibe.
