Our understanding of ourselves as discrete beings separate from each other grows out of conditions of our life in time and space. The less we feel this separation, the more we feel our unification with all other living creatures, the lighter our load, and the more joyful our life will be.
For the body is not one member, but many . . . And if one member suffers, all the members suffer with it; if one member is honored, all the members rejoice with it.
— 1 Corinthians 12:14, 26
A small branch cut off from a big limb is separated from the whole tree. In the same way when a person is in an argument with another person, he is separated from all humanity
— Marcus Aurelius
God created heaven and earth, but they lacked the ability to understand the happiness of their existence. Then God made creatures who could understand the happiness of their existence, and who could create a single body from all of its thinking parts. All people are members of this one body; in order to be happy, they should live in harmony with the will that governs its life. We should live in harmony with this great soul and love it more than we love ourselves.
— Blaise Pascal
We manifest in love our understanding of the unity of our being with others, and in so doing we make our life greater. The more we love, the wider, larger, and more joyful our life becomes.
