In an ideal situation, you should try to meditate in the same space because continued meditation in the same space does build a reservoir of calm energy in the space.
The space should also ideally be clutter-free.
However, if you are waiting to meditate because you do not have a clutter-free space, just go ahead and start.
As your mind gets clearer and calmer, the space around you will begin to clear up.
This is because our outer world becomes a reflection of our inner world.
More about that thought later.
There is no wrong way to meditate.
Think back to a time when you were terrified. Do you remember gasping?
We gasp when we are in fight or flight – we take a deep breath in to make sure that the body has enough oxygen so it is prepared to fight or flee. Along with the gasp, your muscles tense up; your stomach tightens, your shoulders hunch upwards, your forehead scrunches up.
Take a deep breath and let it go with a sigh, notice how your body relaxes. Your shoulders naturally slump downwards. Mental relaxation produces relaxation in the body.
When your mind is relaxed, your body responds.
The mind-body connection is a two-way street.
This means that if we relax the body, we can relax the mind.
This is one of the ways in which a regular meditation practice can help.
Think about what you do when you try meditation, you sit down, close your eyes, and focus on your breath. As you pay attention to your breath it will imperceptibly slow down. As all this happens your body relaxes. This physiological relaxation by itself will change your state of mind.
This is why there is no “wrong” way to meditate.
