Space really means the level of awareness or presence, not thinking. So, can you look at your partner and not think? Two conscious beings realize that the essence of the relationship is the space in it. Even when there is an egoic overlay, it is not too dense or heavy for you to sense the essence underneath it. You don't need to react to the egoic overlay. When you don't react to it you don't strengthen it.
Eckhart TolleWhenever you are able, have a "look" inside yourself to see whether you are unconsciously creating conflict between the inner and the outer, between your external circumstances at that moment - where you are, who you are with, or what you are doing - and your thoughts and feelings. Can you feel how painful it is to internally stand in opposition to what is? When you recognize this, you also realize that you are now free to give up this futile conflict, this inner state of war.
Eckhart TolleHumans eat of the tree of the knowledge of good and bad. Suddenly, they start cutting reality up into bits and pieces, which is what the thinking mind does.
Eckhart TolleYou accept whatever happens in the present moment, the only place where it can happen. Internally, you fully accept what is happening, and what is happening may include an emotion, a stream of anxiety that suddenly comes up within you.
Eckhart Tolle
