If you keep your attention in the body as much as possible, you will be anchored in the Now. You won't lose yourself in the external world, and you won't lose yourself in your mind. Thoughts and emotions, fears and desires may still be there to some extent, but they won't take you over.
Eckhart TolleInner resistance to whatever arises in the present moment pulls you back into unconsciousness. Inner resistance is some form of negativity, complaining, fear, aggression, or anger. This is important because whenever you complain about what somebody else does you're already beginning to fall into that trap of unconsciousness.
Eckhart TolleSurrendering only refers to this moment, whatever "is" at this moment - to accept unconditionally and fully whatever arises at this moment.
