Living in the present can refer to a few different things.
It can mean noticing that all we have is what’s here now and that the idea of a past and future is imagined, as is the idea of a present, and anything we imagine in the past, future, and even present is imagined. It’s all happening within our thought field, within and as mental images and words. It’s all – all our experiences including of the three times and what happens within them – happens within and as what we are.
A less helpful way is to take the idea of living in the present to mean ignoring past and future, or at least making an effort to ignore it. The idea of past, future, present, and what happens in those three times, is essential for us to function and navigate in the world. (It just helps to notice that that’s what they are – ideas.) There is no need to try to ignore these or anything else.
Another less helpful way, which tends to come from an emotional issue and believing certain thoughts, is to take what’s happening here and now – and especially feelings and thoughts – and projecting them into the future, as if they mean something about the future or that it will always be this way, and also projecting them onto the past and present and ourselves as if they mean or can say something real about the past, present, or ourselves.
The first is the cure for the second and third.
