The purpose of life is to attain to mastery; this is the motive of the spirit, and it is through this motive at the back of it that the whole universe is created. The different stages from mineral to vegetable and from vegetable to the animal kingdom, and from animal to man, are the awakening of the spirit towards mastery. By using the mineral and the vegetable kingdoms and controlling the animal kingdom for his service, man shows in the first place that in him is awakened that spirit by which the whole universe was created.
