“Can I meditate laying down?
Or any other position not the normal one?
Thank you :)”
Yes.
You can meditate in any position that works for you.
The seated position commonly associated with meditation called the lotus position is not required to meditate.
Lying down on your bed or in a reclined chair are comfortable positions that help meditation by allowing you to relax all your muscles.
Try different positions and use what works for you.
