This quote is from a program of daily teachings in official website of The Secret and The Power:

Love everything you can. Love everyone you can. Focus only on things you love, feel love, and you will experience that love and joy coming back to you multiplied! The law of attraction must send you back more things to love. As you radiate love, it will appear as though the entire Universe is doing everything for you, moving every joyful thing to you, and moving every good person to y0u. In truth, it is.
