Attachment is the food for the mind to continue. Non-attached witnessing is the way to stop it without any effort to stop it. And when you start enjoying those blissful moments, your capacity to retain them for longer periods arises. Finally, eventually, one day, you become master. Then when you want to think, you think; if thought is needed, you use it; if thought is not needed, you allow it to rest. Not that mind is simply no more there: mind is there, but you can use it or not use it. Now it is your decision. Just like legs: if you want to run you use them; if you don’t want to run you simply rest — legs are there. In the same way, mind is always there.
When I am talking to you I am using the mind — there is no other way to talk. When I am answering your question I am using the mind — there is no other way. I have to respond and relate, and mind is a beautiful mechanism. When I am not talking to you and I am alone, there is no mind — because it is a medium to relate through. Sitting alone it is not needed.
You have not given it a rest; hence, the mind becomes mediocre. Continuously used, tired, it goes on and on and on. Day it works; night it works. In the day you think; in the night you dream. Day in, day out, it goes on working. If you live for seventy or eighty years it will be continuously working.
