Work is also a prayer, not in the form of words but actions. When we love what we do, the doing become a meditation, the mind becomes creative, and the body become joyful.
But when we do not love the work we do, then the prayer is filled with un-love energies, the action is not powerful, and the body becomes weak and ill.
Do what you love. Start with that. Then the doing becomes natural and full of Love. It is one way to cherish yourself and honour your purposes. And through the doing, you get to share your deepest Love with the world.
