Living without thinking, and a conjecture

I saw this video the other day, wherein Gary Weber described his experience of having his thoughts slow down and stop. At the time he was a high-powered executive and when he went to work in the morning, he expected that the absence of thoughts would be a problem for conducting business. But he found that he was still entirely functional. The absence of thoughts brought him peace and joy, without any apparent downside.

I've once or twice had a similar experience but for me it's not lasted more than five or ten minutes. The onset when it has happened has been astonishing. Thoughts just come to a stop, and whatever I was about to think about, it seems like it can wait until later.

When I look at what prevents this happening more often, it's a couple of things. One is that I suffer from a belief that if I'm thinking about something, it must be important and I'd better be careful not to forget it, so I need to continue thinking about it. Another is a belief that thinking will protect me from harm, because thinking is (allegedly) a good way to anticipate and avoid potential problems. But that's not really borne out by experience: thinking, at least of the gadfly variety, is far more likely to distract me from things of real importance.

I was thinking about Scott Kiloby's exercise of resting in awareness, and thinking that it's a nice way to have this thought-free experience for a few seconds. In those seconds, there is an absence of the usual sorts of suffering that one experiences on a daily basis. One is not concerned about the future of one's career or relationship or health. One does not suffer self-esteem issues or painful memories of childhood or family interactions. One simply experiences what is present in the moment in a peaceful way. And thoughts are conspicuous by their absence.

Having had the experience of thoughtlessness and found it quite pleasant. I'm interested in recapturing it, and I wonder if it might be possible to remain in the resting-in-awareness exercise for a minute, and later an hour, and later an entire day, and eventually all the time. When I try to do this, what comes up to hinder my attempt?

I usually start with my eyes closed, and it's simply not practical to go through my day with my eyes closed. But I can continue with the eyes open, focusing on body sensations like breathing or warmth to avoid getting too engaged in thoughts. Next comes the fear that without thoughts, I will lack ambition, and without ambition, I won't accomplish anything. Rationally I know that my thoughts often get in the way of ambitions more than helping with them. And I know I'll run into the belief that thinking is necessary for safety, and again rationally I know that's not the case. I think this is something to continue tinkering with, and see if I can get anywhere with it.
