Meditation: The aim is to make it simple.

Daily mediation is a simple thing to do.
It is how you look at it and how you think about it that makes it complicated.
Meditation comes in several forms, it is up to you to find your own way,
the key is to relax, the type of relaxing that calms your body
totally so you can reach the "meditative-state" of being completely relaxed without falling asleep.
And 5 to 20 minutes will just be fine.
If you do not succeed at once, which most people do, then try once more until you make it. Remember that practice makes perfect.
