They say, "What was, is, and will be; if that is the same substance or life it is not subject to change, nor does it develop." Yet a different grade which we are capable of grasping gives us the feeling that it is a development rising from matter. The great ones, the meditative souls who sat in the wilderness and the forests and communicated with the life around them, realized this truth, and very often they experienced a greater harmony, peace and upliftment where there was no visible life. Life is intelligence, even in the rock, and the more one communicates with life, the more one feels that even the rock is not without life, that through it pulses the blood of the universe.
