Virtues are in the middle, the royal way about which the saintly elder (Saint Basil the Great) said, "Travel on the royal way and count the miles." As I said, the virtues are at the midpoint between excess and laxness. That is why it is written, "Do not turn to the right or the left" (Prov 4:27) but travel on the "royal way" (Num. 20:17). Saint Basil also says, "The person who does not allow his thoughts to incline towards excess or deprivation but directs it to the midpoint, that of virtue, is upright in heart."
