I think it’s always there, like the bar that runs along all the words in Sanskrit, but we just don’t notice it. Then sometimes we notice it it specifically, and it stands out, and then our minds get dull again and can’t see it anymore. Over time, as the mind becomes slowly, increasingly sharp and pure, through a practice like Vipassana, is becomes gradually increasingly visible in everyday life. But as it becomes visible, it’s also normal, and taken as a given. So life seems to become increasingly pervaded by it, in a way that seems natural because it was actually always there the whole time.
