Without expectation, do something for love itself, not for what you may receive. Love in action is what gives us grace. We have been created for greater things – to love and to be loved. Love is love – to love a person without any conditions, without any expectations. Small things, done in great love, bring joy and peace. To love, it is necessary to give. To give, it is necessary to be free from selfishness.
–Saint Teresa of Calcutta (1910-1997)

This spiritual food…

Oh, did spiritual persons but know how much good and what great abundance of spirit they lose through not seeking to raise up their desires above childish things, and how in this simple spiritual food they would find the sweetness of all things, if they desired not to taste those things (passing diversions and distractions)! But such food gives them no pleasure.
–Saint John of the Cross (1542-1591)
