Mark the Ascetic - On the Spiritual Law 75-77

75. Anyone who praises his neighbor out of hypocrisy will later abuse him and bring disgrace upon himself.
76. He who is ignorant of the enemy's ambush is easily slain; and' he who does not know the causes of the passions is soon brought low.
77. Knowledge of what is good for him has been given to everyone by God; but self-indulgence leads to negligence, and negligence to forgetfulness.
