an improper winking one may be branded as double-faced and double-tongued

"It is possible that on account of an inappropriate act of beckoning or an improper winking one may be branded as double-faced and double-tongued. Perchance one may possess this bad habit as long as he is alive and imagine himself to be morally healthy, sound and pure. Therefore, it is essential for an individual to take care, like a devoted and sympathetic physician, of his spiritual and moral health and constantly keep an eye on his own deeds and habits, like a careful and vigilant nurse, and never fall short of his duty. He should know that none of the diseases of the heart is more concealed and elusive, and at the same time so fatal, than this disease, and no nurse should be more sympathetic and kind than an individual to himself."
