I really mean that: the reason we forget and get distracted is because of the ego. Vigilance just creates the ego as the enforcer, the doer, to own the insight. Without the ego, there is no such thing as distraction. If you see the reality of what you are for one moment, you will never become distracted ever again. The whole remembering/forgetting story is simply like tossing and turning in your sleep of which you have no control. It is a good sign, however,that soon you will open your eyes. Please do not take this as something to get reactive to. I don't think of you any differently than I think of myself. Even though I don't know you. But this is what my teacher told me, and I didn't believe him and kept trying to be vigilant, which he also encouraged, but laughed at. When I saw what he was talking about I knew he had been right. He also never put himself as above me and I don't want to give you that impression that I feel above you.
I think the value of trying to remain vigilant is not because we will succeed someday! LOL NO! But that we will have the insight that it is the false sense of self trying to be vigilante. I think this is the whole point of that practice. Otherwise people might not know how tenacious the ego is. It is basically everything that everybody knows about themselves. That is why the Buddhists say there is NO self. Not that there is no body, but everything we think we are besides this body, IS the ego. Everything. So anything anybody does is bound to be egotistical. There is no shame in it. We are all like that. And that is the mess we are all in. Like quicksand. I am NOOO stranger to being an egotistical dream character. Even now, when I have to type out thoughts, I have to let the ego do it while I watch! The ego is the one who DOES things. But really the ego is a dream and things happen on their own by cause and effect when conditions allow. There is no freewill, etc.... This is all a dream!!!
And I encourage you to be vigilante! While you are being vigilante, simply look and see that it is the ego! But you may have to bring you vigilance to a one-pointed laser-like concentration at the limits of what the ego is capable of. That is a good way for the ego to commit suicide momentarily. Of course it will pop up a moment later again, but in that gap you can see something amazing that you will never unsee.
