Bless me into usefulness.

“The first way [to direct your compassion and make it active] is to pray to all the buddhas and enlightened beings, from the depths of your heart, that everything you do, all your thoughts, words, and deeds, should only benefit beings and bring them happiness. In the words of one great prayer: ‘Bless me into usefulness’. Pray that you benefit all who come in contact with you, and help them transform their suffering and their lives.”
