Because our inner self is connected with heaven. That's why Lao Zi say, "Ten thousands things are one." And if we reach that oneness, that greatness within us, then nothing we can not do. We will have all kinds of miraculous power, we will be able to solve all kinds of situations in life. We will be able to understand all kinds of religious scriptures without anyone having to preach to us. We will keep all kinds of virtuous disciplines without anyone having to impose it on us. We will be loving with each other without anyone having to teach us to do so, and we will have peace within our heart and then the peace will radiate outside and help more to make peace on earth.
