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.
~ Eckhart Tolle
