"Do you have patience to wait till your mud settles and the water is clear? Can you remain unmoving till the right action arises by itself?" - Lao Tzu
Although it is virtually impossible to actually describe what it is we are trying to achieve with meditation, I do think it helps to give ourselves clues. As Lao Tzu says above what we are aiming for is simplicity itself, all we are trying to do is sit still until the "mud" settles and IF we can achieve that without any "effort" (effort is thinking, non-effort is stillness) whatsoever, then what is needed will be given to us.
The trouble is we either complicate it with thinking or we simply don't sit around long enough until "the waters are clear".
Think of it as a snow shaker (Google "snow shaker" if you don't know what one is). All you really need to know is that thoughts shake the snow shaker and non-thinking stops the shaking, which allows the snow to settle. The idea is simplicity itself, all we have to do is to stop thinking long enough for the snow to settle and the benefits will come to us, yet in practise it is hard to stop thinking long enough for the snow to settle and that is exactly why meditation is so hard at first and takes patience and practise to master.
So, my point: I think it is important that people know that one 5min session will give you barely anything in return, however if you work on it and slowly build up your sessions so that you are regularly meditating for 20-30min at a time then, and only then, will you begin to experience the fruits of your patient labour as the mind has to settle down completely before the "magic" happens and getting it to settle down, although very simple in theory, takes lots of practise because sitting quietly and not thinking, or maybe a better description is "not being attached to, or attracted by, any thoughts" is so, so, alien to us.
