Meditation is something that gets mentioned a lot to me as a psychotherapist. Mostly in terms of how a person has tried to meditate but can't. Or that they meditate in the morning but still feel stressed and so it isnt 'working.'
To me, what IS meditation is actually not fully understood. Typically we think of the person crosslegged on the floor, eyes closed, incense burning, chanting a mantra etc. Yes, that is certainly a WAY to meditate but it isnt exactly WHAT meditation is or the only way to get in that state.
You see a brain scientist views Meditation as a 'state' that 'state' is then measurable and observable for a scientist. They use MRI machine, ECG machine etc. to measure and observe what happens to a persons brain when in a meditative state. Below I have included some links about this if you are interested in learning more about this fascinating subject.
You have heard of Mindfulness? It is a very popular concept these days. I completed a course in Mindfulness with Leiden University in conjunction with Oxford University and found what I learned to be very revealing and helpful as a therapist.
