You haven't changed. You may say: 'I'm full of love, I'm full of truth, I'm full of knowledge, I'm full of wisdom.' I say: 'That's all nonsense. Do you behave? Are you free of fear? Are you free of ambition, greed, envy and the desire to achieve success in every field? If not, you are just playing a game. You are not serious.'
