Sadhguru
Why can't my body sit still when I try to meditate?
Allotted karma and restless meditation
In prarabdha, a certain amount of your energy is dedicated to physical activity, and similarly to mental and emotional activity. When allotted physical karma is not taken care of, the body won't let you sit for meditation.
When your allotted physical karma has not been taken care of, if you try to sit and meditate, your body won't let you sit.
