In the tenth and subsequent Urantia Foundation printings, "light-hearted" was changed to "lighthearted."
P1206:2, 110:3.4
I cannot but observe that so many of you spend so much time and thought on
mere trifles of living, while you almost wholly overlook the more essential
realities of everlasting import, those very accomplishments which are concerned
with the development of a more harmonious working agreement between you and
your Adjusters. The great goal of human existence is to attune to the divinity
of the indwelling Adjuster; the great achievement of mortal life is the attainment
of a true and understanding consecration to the eternal aims of the divine
spirit who waits and works within your mind. But a devoted and determined
effort to realize eternal destiny is wholly compatible with a light-hearted
and joyous life and with a successful and honorable career on earth. Co-operation
with the Thought Adjuster does not entail self-torture, mock piety, or hypocritical
and ostentatious self-abasement; the ideal life is one of loving service rather
than an existence of fearful apprehension.
