Buddha said: One flower is one world, one grass is one paradise, one leaf is one Tathagata, one sand is one bliss, one square is one pure land, one smile is one fate. One thought, one tranquility, all this is a state of mind. If there is nothing in the mind, one flower and one world, one grass and one heaven can be understood. One flower and one grass is the whole world, and the whole world will be empty like flowers and grass. There are Buddhas everywhere, and all living beings and everyone are Buddhas.
