" All the differences in the outside world are the outcome of your mental modifications. For example, imagine you have not seen your father since your birth and he returns when you are ten years old. He knocks at your door. Opening it, you see a strange face. You run to your mama saying, “Mama, there’s a stranger at the door.” Your mama comes and sees her long-lost husband. With all joy she receives him and introduces him as your father. You say, “Oh, my Daddy!” A few minutes before, he was a stranger; now he has become your daddy. Did he change into your daddy? No, he is the same person. You created the idea of “stranger,” then changed it to “Daddy.” That’s all. The entire outside world is based on your thoughts and mental attitude. The entire world is your own projection. Your values may change within a fraction of a second. Today you may not even want to see the one who was your sweet honey yesterday. If we remember that, we won’t put so much stress on outward things. "
