We live on the surface of ourselves - just at the fringe, the boundary. The senses are just on the boundary and your consciousness is way deep down at the center.
Senses are just in between, just in the middle. At one side is consciousness, at another side is the world of objects. Senses are just in the middle - between the two. From the senses you can move either way: either you can go to the objects or you can go to the center. Either way the distance is the same.
You are at the senses. That is why one of the most famous Zen Masters, Bokuju, has said that nirvana and the world are the same distance away. So do not think that the nirvana is very far away. The world and the nirvana, this world and that other world, are both at the same distance.
