This indicates not only the power of cooperation in pregnancy, but also all the immense influence and background that lies behind a human birth. Thousands of generations of experience lie latent in the sperm and ovum. It is also eternal in that although the body carrying it dies, the sperm, if it passes on in reproduction, carries on living. It therefore has an unbroken life back to the beginning of life. It can therefore represent your whole long history, all your forebears in the male line, all your potential for the future.
