What actually keeps the mind tied to the body?

Lama Ole’s answer:

Habit! At this very moment you are connected to all energies and places everywhere. What keeps you in your body is an ego-illusion. There is actually no difference at all between the vibration in your skin and the vibration everywhere. And you don’t have to leave the body to become enlightened. What keeps you tied to your body now is habit. And habit again is what will try to hold you back while dying. This will continue until the ego-illusion falls away.
