And when the spiritual person advances still further he arrives at the stage of the mineral kingdom. He becomes as a rock; a rock for others to lean on, to depend upon; a rock that stands unmoved amidst the constantly moving waves of the sea of life; a rock to endure all things of this world whose influence has a jarring effect upon sensitive human beings; a rock of constancy in friendship, of steadfastness in love, of loyalty to every ideal for which he has taken his stand. One can depend upon him through life and death, here and hereafter. In this world where nothing is dependable, which is full of changes every moment, such a soul has arrived at the stage where he shows through all these changes that rock-like quality, proving thereby his advancement to the mineral kingdom.
