I think that doubt is a lot like anxiety, in that even though they both present themselves as thoughts, they seem to innately command more attention than a thought such as: "oh, I need to go the shop." As a result, you start to think of them as coming from somewhere other than thought and this separation causes the experience to kind of double down. You get anxious of being anxious (anxiety sensitivity], or subconsciously doubtful about everything. But they are just thoughts. And if you acknowledge them you can see what's behind them and let it go like you would any other thought or feeling. Often enough, there's nothing behind them at all and, in acknowledging them, they ceases to exist This reminded me of a chapter I read entitled "The Possible and the Real" in Henri Bergson's book The Creative Mind . He states that most humans naturally, and incorrectly, presume that possibility precedes reality. Instead, it is reality that precedes possibility. The present moment is the constant process of chaos forming into an ordered reality. Once this reality has created itself "its image is reflected behind it in the indefinite past; thus it finds it has been, at all times, possible; but just at the very moment where it begins to have always been... The possible is thus the mirage of the present in the past. And as we know that the future will end up becoming the present, as the effect of the mirage continues unabatedly to produce itself, we tell ourselves that in our current present, which will be the past of tomorrow, the image of tomorrow is already contained although we haven't come to grasp it. And precisely there lies the illusion ". I found the chapter split into 3 parts online if you're interested. Part 3 contains the meat of the idea I mentioned above:At the end of 2016, I read something which took me most of 2017 to internalise: "doubt must come to an end." I haven't been able to find that quote's source ever again. The insight that phases of doubt are just that, phases, has been meaningful to me.
Again, you can’t connect the dots looking forward; you can only connect them looking backward. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
