The silence of meditation is not the silence of a graveyard; it is the silence of a garden growing. There is no deadness in a garden, but in that all-pervading silence an intense activity is going on in the ground which will later take form as buds, blossoms and fruit. So, too, in meditation there is not a blankness, but a rhythmic activity of the Spirit. As the mind exhausts itself the Spirit comes through, and we are in the realm of heaven. True, we are still on earth, our feet are solidly on the ground -- the holy ground of spiritual awareness.
Gratitude is the most fruitful way of deepening your consciousness that you are not an "accident", but a divine choice. It is important to realize how often we have had chances to be grateful and not have used them. When someone is kind to us, when an event turns out well, when a problem is solved, a relationship restored, a wound healed, these are very concrete reasons to offer thanks.
What fascinates me so much is that every time we decide to be grateful, it will be easier to see new things to be grateful for. Gratitude begets gratitude, just as love begets love.
