What can be added to the happiness of a man who is in health, out of debt, and has a clear conscience?

  --Adam Smith, economist (1723-1790)

(100:4.3) But the great problem of religious living consists in the task of unifying the soul powers of the personality by the dominance of LOVE. Health, mental efficiency, and happiness arise from the unification of physical systems, mind systems, and spirit systems. Of health and sanity man understands much, but of happiness he has truly realized very little. The highest happiness is indissolubly linked with spiritual progress. Spiritual growth yields lasting joy, peace which passes all understanding.

(110:1.3) Although the divine indwellers are chiefly concerned with your spiritual preparation for the next stage of the never-ending existence, they are also deeply interested in your temporal welfare and in your real achievements on earth. They are delighted to contribute to your health, happiness, and true prosperity. They are not indifferent to your success in all matters of planetary advancement which are not inimical to your future life of eternal progress.

(156:2.7) Said Jesus: "My disciples must not only cease to do evil but learn to do well; you must not only be cleansed from all conscious sin, but you must refuse to harbor even the feelings of guilt. If you confess your sins, they are forgiven; therefore must you maintain a conscience void of offense."

(160:4.2-4) The essentials of the temporal life, as I see them, are:
    1. Good physical health.
    2. Clear and clean thinking.
    3. Ability and skill.
    4. Wealth—the goods of life.

    Adam Smith was a Scottish economist and philosopher who was a pioneer of political economy and key figure during the Scottish Enlightenment. Also known as "The Father of Economics" or "The Father of Capitalism", he wrote two classic works, The Theory of Moral Sentiments (1759) and An Inquiry into the Nature and Causes of the Wealth of Nations (1776). The latter, often abbreviated as The Wealth of Nations, is considered his magnum opus and the first modern work of economics. In his work, Smith introduced his theory of absolute advantage.
    Smith studied social philosophy at the University of Glasgow and at Balliol College, Oxford, where he was one of the first students to benefit from scholarships set up by fellow Scot John Snell. After graduating, he delivered a successful series of public lectures at the University of Edinburgh, leading him to collaborate with David Hume during the Scottish Enlightenment. Smith obtained a professorship at Glasgow, teaching moral philosophy and during this time, wrote and published The Theory of Moral Sentiments. In his later life, he took a tutoring position that allowed him to travel throughout Europe, where he met other intellectual leaders of his day.
    Smith laid the foundations of classical free market economic theory. The Wealth of Nations was a precursor to the modern academic discipline of economics. In this and other works, he developed the concept of division of labour and expounded upon how rational self-interest and competition can lead to economic prosperity. Smith was controversial in his own day and his general approach and writing style were often satirised by writers such as Horace Walpole.
