I am practising regular meditation at the moment. And currently doing three sittings a day, one in the morning, one at noon, and one in the evening. Just for 30 minutes each time, although I am contemplating the idea of doing a 2 hour long sit on a Sunday afternoon, as I want to experiment with sitting for longer to see if it will help me settle into deeper states of serenity. Out of the three daily sittings, the morning one is the hardest, I often battle with drowsiness in the first sitting (even with coffee) and I was experimenting this morning with trying to remain lucid during the drowsy surreal states of mind that arise when one is on the edge of sleep. I sometimes experience what are known as hypnagogic hallucinations just as I am about to doze off which alters my perception a bit and things can get quite weird, so I practise staying still and being mindful during those experiences, which can generate some interest in what is happening and help me stay awake.
The easiest of the three meditations is the evening one I find, I seem to feel a much stronger connection between mind and body and a greater depth of stillness and can feel energy that at times feels otherwordly but profoundly peaceful, with some interesting visual effects behind closed eyelids. The evening meditation also seems to go by the fastest, and I am often suprised by how quickly the time seems to go in the evening sitting. The morning meditation however seems to drag on, one minute can feel like ten and it can be very challenging to stay sat there.
It is interesting how one's perception of time changes, and how the mind seems to be able to alter how slow or quickly the passage of time goes by, but only relative to one's mind, everyone else's perception of time is not effected by ours. I am reminded of how Einstein said that time is relative, that time can be a unique experience to us all. This goes quite deep when you think about other species of life. Plants for example have a completely different sense of time to us humans. Their world seems very slow to us, but to them it is normal. Birds apparently experience time seven times faster than we do, and insects even more so, to insects we appear to move very slowly. And there are apparently bacteria that live deep under the ocean floor that are as old as 100 million years and reproduce once every 10 000 years.Yet despite our differences in speed, to each species of life their experience of time feels normal.
An interesting thing that I experimented with one time in music was slowing down bird song, and when I did this it sounded like a human singing, and vice versa when I sped up the human voice it sounded like a bird singing. I saw one time on a documentary that when humans are sped up seven times faster than normal on camera their movement looks similar to the movement of birds.
Perception of time is an interesting phenomenon, time really is relative. But one thing we can all be sure of, is whatever species of life - time comes for all.
