Pleasure

“Anything that refreshes you without diminishing, distracting or destroying the final goal is a legitimate pleasure. Any pleasure that jeopardizes the sacred right of another is an illegitimate pleasure. Any pleasure no matter how good if not kept in balance will distort reality or destroy appetite. All pleasure is bought with a price; for the legitimate pleasure you pay before partaking; for the illegitimate you pay after partaking.” -RZ

Sin

“Whatever weakens your reasoning, impairs the tenderness of your conscience, obscures your sense of God or takes away your relish for
spiritual things in short if anything increases the power and authority of the flesh over the spirit that to you become sin however good in itself.” – SW
