Virtues to strive for concerning one’s own spiritual growth and development while interacting with other human beings

It is incumbent upon you to have union and harmony and love and uprightness, and to be characterized with the morals of your Lord, the Clement; to walk in the highway of equity and beneficence. Be ye manifestations of the mercy of God, dawning-places of the light of His great bounty, and arise with all steadfastness, truthfulness, trustworthiness, compassion, modesty, love and accord with the people of the world, no matter of what community they may be; inasmuch as it behooveth the light to shine even upon the rocks in the field, and the soul is qualified for quickening individuals, even though they be of the ugliest and most disagreeable form, and a pure tree is adapted to bestow a blessed fruit even upon those who throw stones at it. (‘Abdu'l-Baha, Tablets of ‘Abdu'l-Baha v2, p. 271)
