Wallace D. Wattles on the Secret of All Attainment

"There is a constructive, or integrating principle in nature, and a destructive, or disintegrating principle - power applied through the constructive principle builds, forms and integrates; it draws atoms and forms together - power applied through the destructive principle dissolves and disintegrates; it disperses atoms and forms, and throws them apart - to learn how to make every thought and action constructive, is to master the secret of all attainment."
