four qualities

"There are four qualities which I love to see manifested in people: first, enthusiasm and courage; second, a face wreathed in smiles and a radiant countenance; third, that they see all things with their own eyes and not through the eyes of others; fourth, the ability to carry a task, once begun, through to the end." - Baha'u'llah

None must contend with those who wield authority over the people

"None must contend with those who wield authority over the people; leave unto them that which is theirs, and direct your attention to men's hearts."
-Baha'u'llah

Patience

He, verily, shall increase the reward of them that endure with patience.
-Baha'u'llah

Let not your heart be offended

"Let not your heart be offended with anyone. If someone commits an error and wrong toward you, you must instantly forgive him. Do not complain of others. Refrain from reprimanding them, and if you wish to give admonition or advice, let it be offered in such a way that it will not burden the bearer. Turn all your thoughts toward bringing joy to hearts. Beware! Beware! lest ye offend any heart." Abdu'l-Baha
