In investigating protoplasm we are made to realize the wonderful qualities of its principal constituent—­Carbon.  Carbon is the wonder worker of the elements.  Manifesting in various forms, as the diamond, graphite, coal, protoplasm—­is it not entitled to respect?  The Yogi Teachings inform vis that in Carbon we have that form of matter which was evolved as the physical basis of life.  If any of you doubt that inorganic matter may be transformed into living forms, let us refer you to the plant life, in which you may see the plants building up cells every day from the inorganic, chemical or mineral substances, in the earth, air, and water.  Nature performs every day the miracle of transforming chemicals and minerals into living plant cells.  And when animal or man eats these plant cells, so produced, they become transformed into animal cells of which the body is built up.  What it took Nature ages to do in the beginning, is now performed in a few hours, or minutes.

The Yogi Teachings, again on all-fours with modern Science, inform us that living forms had their beginning in water.  In the slimy bed of the polar seas the simple cell-forms appeared, having their origin in the transitional stages before mentioned.  The first living forms were a lowly form of plant life, consisting of a single cell.  From these forms were evolved forms composed of groups of cells, and so proceeded the work of evolution, from the lower form to the higher, ever in an upward path.

As we have said, the single cell is the physical centre, or parent, of every living form.  It contains what is known as the nucleus, or kernel, which seems to be more highly organized than the rest of the material of the cell—­it may be considered as the “brain” of the cell, if you wish to use your imagination a little.  The single cell reproduces itself by growth and division, or separation.  Each cell manifests the functions of life, whether it be a single-celled creature, or a cell which with billions of others, goes to make up a higher form.  It feels, feeds, grows, and reproduces itself.  In the single-celled creature, the one cell performs all of the functions, of course.  But as the forms become more complex, the many cells composing a form perform certain functions which are allotted to it, the division of labor resulting in a higher manifestation.  This is true not only in the case of animal forms, but also in the case of plant forms.  The cells in the bone, muscle, nerve-tissue and blood of the animal differ according to their offices; and the same is true in the cells in the sap, stem, root, leaf, seed and flower of the plant.

As we have said, the cells multiply by division, after a period of growth.  The cell grows by material taken into its substance, as food.  When sufficient food has been partaken, and enough new material accumulated to cause the cell to attain a certain size, then it divides, or separates into two cells, the division being equal, and the point of cleavage being at the kernel or nucleus.  As the two parts separate, the protoplasm of each groups itself around its nucleus, and two living forms exist where there was but one a moment before.  And then each of the two cells proceed to grow rapidly, and then separate, and so on to the end, each cell multiplying into millions, as time passes.
