According to Osho, giving up chewing tobacco cannot be imposed from outside or by moralizing; the urge to change another is ego and destroys love. Don't condemn or feel superior; offer compassion and friendship. Real change arises only from one’s own insight; in a loving, non-coercive space, habits drop naturally—control breeds resistance.
You can’t force someone to quit; be kind and stop nagging—when they see it clearly themselves, they’ll let it go.
