Mind doesn´t exist as an entity – this is the first thing. Only thoughts exist.
The second thing: thoughts exist separate from you, they are not one with your nature, they come and go – you remain, you persist. You are like the sky: it never comes, it never goes, it is always there. Clouds come and go, they are momentary phenomena, they are not eternal. Even if you try to cling to a thought, you cannot retain it for long; it has to go, it has its own birth and death. Thoughts are not yours, they don´t belong to you. They come as visitors, guests, but they are not the host.
Watch deeply, then you will become the host and thoughts will be the guests. And as guests they are beautiful, but if you forget completely that you are the host and they become the hosts, then you are in a mess. This is what hell is. You are the master of the house, the house belongs to you, but the guests have become the masters. Receive them, take care of them, but don´t get identified with them; otherwise they will become the masters.
The mind becomes the problem because you have taken thoughts so deeply inside you that you have forgotten completely the distance; that they are visitors, they come and go. Always remember that which abides: that is your nature, your tao. Always be attentive to that which never comes and never goes, just like the sky. Change the gestalt: don´t be focused on the visitors, remain rooted in the host; the visitors will come and go.
