Life is the glory of the Spirit, since "to exist" and "to live" are different things.
The rocks, the sea, the winds, the fire,  exist but are not beings with intelligent life, neither with consciousness that vibrate with feelings, with reasons, dreams and ideals. We repeatedly forget  about the main reason to be and then, we merely start to exist, becoming like tombs. But to live means another thing. When we truly learn the meaning of "to be", then we stop being living dead and we become living beings in the totality. This happens when we know Love as a direct experience, when we can express true Love by sharing, communicating and not only by watching without any action.
 Life is the glory of the Spirit and this wonderful gift is the gift of Giving and Receiving.
