It's from the Huayan Sutra of Dafang Guangfo: "Good! Buddha! Today, you want to have more benefits, more seclusion, sorrow for the world, and enjoy heaven and man, so you ask. Buddha! If the bodhisattvas make good use of their hearts, they will win all the wonderful merits; In the Buddhism, the heart is not hindered, and the way to live, come, and be a Buddha today; Live with all beings and never give up; Such as the various dharma phases, you can understand them; Break all evil, with all good; Be like Pu Xian, the color image is the first, and all the wishes must be sufficient; In all laws, he is uncomfortable and is the second mentor of all beings. Buddha! What can you do with your heart to win all the wonderful merits? "

Being kind to everything means that the Bodhisattva treats all sentient beings equally, which does not hinder people and all sentient beings.
