Vulnerable patients recovering from destructive habits require an environment free from injurious influences.

Original passage

Many seek medical advice and treatment who have become moral wrecks through their own wrong habits. They are bruised and weak and wounded, feeling their folly and their inability to overcome. Such ones should have nothing in their surroundings to encourage a continuance of the thoughts and feelings that have made them what they are. They need to breathe an atmosphere of purity, of high and noble thought. How terrible the responsibility when those who should give them a right example are themselves enthralled by hurtful habits, their influence affording to temptation an added strength!
