concretely, his bliss, his wisdom, and his power. Adam and Eve, and the tree in the midst of the garden! After man and woman, a tree is perhaps the most significant symbol in the world: every tree is the Tree of Life in the sense that it is a representation of universal becoming. To say that all things have for their mother _prakriti_, undifferentiated substance, and for their father _purusha_, the creative fire, is vague and metaphysical, and conveys little meaning to our image-bred, image-fed minds; on the physical plane we can only learn these transcendental truths by means of symbols, and so to each of us is given a human father and a human mother from whose relation to one another and to oneself may be learned our relation to nature, the universal mother, and to that immortal spirit which is the father of us all. We are given, moreover, the symbol of the tree, which, rooted in the earth, its mother, and nourished by her juices, strives ever upward towards its father, the sun. The mathematician may be able to demonstrate, as a result of a lifetime of hard thinking, that unity and infinity are but two aspects of one thing; this is not clear to ordinary minds, but made concrete in the tree--unity in the trunk, infinity in the foliage--any one is able to understand it. We perceive that all things grow as a tree grows, from unity to multiplicity, from simplicity and strength to beauty and fineness. The generation of the line from the point, the plane from the line, and from the plane, the solid, is a matter, again, which chiefly interests the geometrician, but the inevitable sequence stands revealed in seed, stem, leaf, and fruit: a point, a line, a surface, and a sphere. There is another order of truths, also, which a tree teaches: the renewal of its life each year is a symbol of the reincarnation of the soul, teaching that life is never-ending climax, and that what appears to be cessation is merely a change of state. A tree grows great by being firmly rooted; we too, though children of the air, need the earth, and grow by good deeds, hidden, like the roots of the tree, out of sight; for the tree, rain and sunshine: for the soul, tears and laughter thrill the imprisoned spirit into conscious life. We love and understand the trees because we have ourselves passed through their evolution, and they survive in us still, for the arterial and nervous systems are trees, the roots of one in the heart, of the other in the brain. Has not our body its trunk, bearing aloft the head, like a flower: a cup to hold the precious juices of the brain? Has not that trunk its tapering limbs which ramify into hands and feet, and these into fingers and toes, after the manner of the twigs and branches of a tree?
