Beware! Beware!

...Turn all your thoughts toward bringing joy to hearts.

Beware! Beware! lest ye offend any heart.
Assist the world of humanity as much as possible.
Be the source of consolation to every sad one, assist every weak one, be helpful to every indigent one, care for every sick one, be the cause of glorification to every lowly one, and shelter those who are overshadowed by fear.
In brief, let each one of you be as a lamp shining forth with the light of the virtues of the world of humanity. Be trustworthy, sincere, affectionate and replete with chastity...
