I have been pondering on this for a long time. Time is supposed to be an illusion, so is space. Can someone explain what is the term 'timelessness' like in actual experience? And how is time created as an illusion? Thank you.
answer is no-one knows, because we're pretty much at the stone-age stage of our cognitive sciences. (we only recently abandoned lobotomies as a valid procedure). the analogy/metaphor that made the most difference to me, in terms of being able to integrate a lot of different material using it, went as follows. (if it helps you, great. it helped me to grapple with these ideas.)
imagine you enter a dark room, filled with objects, armed with a torch. you switch the torch on and see a teddy bear. then you point it up and see a ceiling. then you point it down and see a magazine. because the torch was pointed sequentially, you experience a sequential awareness of teddy bear, ceiling, magazine, proceeding after each other. this is subjectively experienced as time (because of the subjective experience of "before" and "after"). however, no such actual, absolute time exists, because the objects (teddy bear, ceiling, magazine) all existed at all stages. (they didn't flicker in and out of existence when we shone a light on them). this is simply easier to accept with objects, because we commonly attribute an ongoing pervasive existence to objects, that we don't commonly attribute to events. the key is to understand that the same rules apply to events as to objects, and that when we shine the torch of attention on a sound, rather than a sight, it would be as intrinsically timeless (and subjectively sequential) as the object/sight.
for example, see how we are likely to expect a bird to have a continuous existence across days, but a bird-song not to. in our common categorization of experiences, "bird" is an object, and "song" is an event. the reality is that "objects" have no more weight and reality than bird-song (nor any less). they just take longer to fade away, and the sense data about them (sight, on the back of waves) persists for much longer than the sense data about song ("sounds", on the back of waves). so, if we understand that ALL our objects are actually events (or processes) of differences strengths and duration, then the dark room is actually filled with timeless possibility (or emptiness), possibilities that we assemble and collapse into so-called events and objects, under pressure from karma.
fwiw, it makes sense to me that we attribute pervasive continuity to objects mainly because of sight. sight is a largely pervasive sense and our sight experiences guide us to have tactile experiences (move our arms and legs) that we interpret as depth, extension and dimension. the pervasiveness of sights is so much greater than that of sounds that we arbitrarily relegate sound experiences to the category of "event". the reality is that it is ALL events, and the reificaton of light and waves into objects and events by itself produces time subjectively.
anyway. hope it helps.
