We must realize that the human body, the organism of man, with all its faculties, capacities and powers, is but an _instrument_ of the Individual Intelligence; and that every experience in life, every episode in our career, is like a day's work; perfecting the instrument for more and better work, if used rightly; till we advance from height to height of being; to larger and still larger and more glorious fields of work and experience. There would seem to be no limit to this evolution, this upward and onward journey of the human soul. The more good work done, the larger the capacity and the broader the field opening before us. "From height to height the spirit walks." The primary endowment of man is Life and conscious Intelligence, with the power to use both. This would seem to be the only gratuity, and whether we regard it as a blessing or a curse, depends on how we regard and use them. The great majority in all time, through ignorance or recklessness, seem to have misused them. Hence sickness, disease, deformity, and degradation. It is a wonderful thing--this Law of Normal Use--from which health, harmony, comfort, joy, growth, and development result, while misuse and abuse degrade and destroy. Divinity seems to have put within the grasp of man's Intelligence (if he _chooses and wills_) an almost infinite range in power, variety and application, of that subtle and basic Principle of affinity, balance and equilibrium, that unites the atoms in a molecule, or a chemical substance; that law of attraction and repulsion--the Parallelogram of Force--that holds the planets in their orbits. Divinity seems to have taken man into council and offered him, not only the Kingdom of Nature, but the royal domain of his own soul, as a reward for co-operation and loyal service, on condition that he shall use wisely, intelligently, loyally, and kindly, and not misuse or abuse. Is it _worth while_? Will it _pay_? Nor is this all, beneficent as it seems. The whole journey of life on the physical plane here below is so designed and planned as to make the natural aging and decay of the physical body supplement, unfold and develop the Spiritual Body, through the right use of the faculties, capacities, and powers of the Human Soul--the Individual Intelligence. These are aspects, uses and powers of that subtle _something_ we call _Life_; that _Principle_ that "Runs through all time, extends through all extent, Lives undivided, operates unspent." Normal use that insures growth and development, range and power of action, is also, from first to last, a _refining_ process; while misuse and abuse of these powers degrade and brutalize _inevitably_. It follows, therefore, as the bodily structure and functions fail _under normal use_ those of the spiritual body open, develop and unfold. First the seed, then the plant, then the flower and finally the fruit "of a well-spent life."
