No relationship can thrive without the sense of spaciousness that comes with stillness. Meditate or spend silent time in nature together. When going for a walk or sitting in the car or at home, become comfortable with being in stillness together. Stillness cannot and need not be created. Just be receptive to the stillness that is already there, but is usually obscured by mental noise.
If spacious stillness is missing, the relationship will be dominated by the mind and can easily be taken over by problems and conflict.
If stillness is there, it can contain anything.
When you look upon another human being and feel great love toward them, or when you contemplate beauty in nature and something within you responds deeply to it, close your eyes for a moment and feel the essence of that love or that beauty within you, inseparable from who you are,your true nature. The outer form is a temporary reflection of what you are within, in your essence.
That is why love and beauty can never leave you,
although all outer forms will.
Ultimately, of course, there is no other, and you are always meeting yourself.
