Indulgence is a descriptive word in the vocabulary of corporeal sense. Reflection is coincident with spiritual sense.
Their bearing upon human experience is diametrically opposite. One who is passing from indulgence to reflection is passing from drudgery, waste, and inefficiency to rich and gladsome activity; from repeated disappointments to abiding poise and contentment; from servitude to freedom. In the last analysis, he is passing from death unto life.
Indulgence suggests flabbiness, the line of least resistance, unregulated impulses and tendencies. The appeal to indulgence is always from evil, never from good. One indulges evil; one expresses, reflects good.
