Om Swami
Why does my meditation break when I feel my body?
Body movement shakes the mind
When body awareness arises, the mind shakes, thoughts begin and meditation breaks. If meditation breaks, you cannot hold your ishta (chosen deity) steady in the mind, because supreme steadiness is needed.
Awareness of the body will arise in you again and again when you try to meditate, and as soon as it arises, the mind shakes.
