There is a tendency for our minds to shift around a great deal, jumping from one thought to the next. When this happens, the best way to tame the mind is to give it a toy. The best toy we can provide is something that is similar to the mind. It’s not mind itself, but it feels familiar to the mind, almost like a portrait of it. It is like giving a child a doll or a teddy bear, which is small and cuddly and somewhat like the child. It’s like an image of yourself, almost like a surrogate. In meditation, the teddy bear is your breath.
