Meditation consists in learning to focus and to control the mind. When the mind is stilled, then the light of the intellect begins to shine. The mind is ordinarily scattered and dissipated, but gather the mind into one and then the pure light shines in the mirror which is oneself. Speech is the movement by which we go out of ourselves to communicate with another. Meditation takes us within ourselves. It is a process of inward withdrawal, a centering in the place of inner detachment, a staying of the mind upon God.
To acknowledge our ancestors means we are aware that we did not make ourselves, that the line stretches all the way back, perhaps to God; or to Gods. We remember them because it is an easy thing to forget: that we are not the first to suffer, rebel, fight, love and die.
