It is partly physical and partly paraphysical. That s why the mind has the capacity to go through a wall. It s like a magnet - the magnet has a physical limit, but the force of the magnet has a wider range. That means that it has a dimension, but its force extends beyond that dimension. The mind is more like the force of matter.
Mind is like a negative magnetism.
It is like the magnetic power of the body - the body is like the magnet and the power of the body is the mind. I could be sitting in a closed room, but the mind will go out. You have to control the mind, because it can go and roam about, but it can be used if you control it. Let me explain further. The mind is like a gate that stops everything, like the gates of a dam.
