If a tree wants to be strong, it needs a number of roots sent deep into the soil. If a tree has only one root, it may be blown over by the wind.
Look deeply into the nature of your love and find out. The happiness of the other person and your own happiness depend on the nature of your love! Of course you have love in you — but what is important is the nature of that love. All love may begin by being passionate, especially for younger people. But in the process of living together, they have to learn and practice love, so that selfishness — the tendency to possess — will diminish, and the elements of understanding and gratitude will settle in, little by little, until their love becomes nourishing, protecting, and reassuring. ~Thich Nhat Hanh
