The real meaning of the word is life, and is there anything that is not life, whether silent objects or living beings? For instance a person not knowing the secret of the planets, not knowing their influence, their nature, their character what do they say to him? Nothing. He knows that there are planets, and that is all. As far as the science of astronomy goes, a person who has studied it may say that the planets have a certain influence upon the weather and upon the season, but the astrologer will perhaps hear a louder sound from the planets; he can say that the planets have a certain influence upon the individual and upon his life. What do we understand by this? That to one the planet does not speak, to another it speaks whispering, and to yet another it speaks loudly.
