The man who loves God with a true heart, and prizes him above all things, sometimes sheds floods of tears at prayer, and has in abundance of favors and spiritual feelings coming upon him with such vehemence, that he is forced to cry out, “Lord! let me be quiet!” But a man ought not to seek for these sweetnesses and sensible devotions forcibly, for he will be easily deluded by the devil, and will run a risk of injuring his health.
— Saint Philip Neri (1515-1595)
