Vigelance

Such a chaste and holy life, with its implications of modesty, purity, temperance, decency and clean-mindedness, involves no less than the exercise of moderation in all that pertains to dress, language, amusements, and all artistic and literary avocations. It demands daily vigilance in the control of one's carnal desires and corrupt inclinations.
