As salaam alaikum
Meditation is alleviating all thoughts. Ability to focus on a single thought is also its equivalent.
For Muslims the best form of meditation is already assigned by Allah . Salaah. The prayers.
In salaah you get connected to Allah while He communicates to you. This is not uncommon . Most of us know this.
However the point I want to make is something else.
Have you ever considered that there are occasion for all of us where we are able to focus on a particular matter to an extent that we are completely oblivious to all the things happening around us.
These are matters of extreme emergencies.
Let me give a couple of examples.
Your family doctor , whom you trust most, giving you an advice or a prescription for your coronory heart disease.
Nobody has to tell you to pay attention to the doctors advice.
You do that since you know it's worth.
If you are crossing a road and all of a sudden you see a speedy vehicle in your direction, may be only a couple of meters away, you of course go thoughtless here.
You see in these instances we we're able to practise the highest form of meditation without any training.
For a Muslim the life of this world itself is a state of emergency.
So when he stands in salaah he is able to focus on what he reads since he knows the value of the advice given.
He is able to focus also because he is in awe of the advice giver.(Allah) . This point needs a separate discussion.
So salaah is the best form of meditation as well.
Of course the movements are also placed in it for additional benefits for it's readers. However the crux is the guidance for both worlds given through the Qur'an.
