Every room that you ever meditate in will have some background noise going on. In the Lion’s Dance meditation, we use these little noises, instead of allowing them to become distractions. Our focus moves from outside background sounds to inner sounds, up through many levels of meditation. We move up through these mind states by looking ahead each time to the next one, which is a quieter place than the one we’re in now. Eventually we’re able to put our mind on each step any time we want to.
The real goal of meditation is to calm the mind down to the point where we can understand the secret of life: that everything we ever see around us, and everyone we ever meet in our life, is popping out of karmic seeds in our mind. Learn to master the art of meditation, and get to the top, to the meditation where it will be much easier for us to see emptiness directly.
