Eckhart Tolle in his book Stillness Speaks:
"No relationship can thrive without the sense of spaciousness that comes with stillness. Meditate or spend silent time in nature."
"If spacious stillness is missing, the relationship will be dominated by the mind and can easily be taken over by problems and conflicts. If stillness is there, it can contain anything."
Stillness ... a difficult lesson for me to learn.
