"This is the basic trick in getting the mind to settle down in the present moment — you've got to give it something that it likes to stay with. If it's here against its will, it's going to be like a balloon you push under the water. As long as your hand has a good grasp on the balloon, it's not going to pop up, but as soon as you slip a little bit, the balloon pops up out of the water. If the mind is forced to stay on an object that it really finds unpleasant, it's not going to stay. As soon as your mindfulness slips just a little bit, it's gone."
