Kindness

A kindly tongue is the lodestone of the hearts of men.  It is the bread of the spirit, it clotheth the words with meaning, it is the fountain of the light of wisdom and understanding....

(Baha'u'llah:  Gleanings, Page: 289)

Do not be content with showing friendship in words alone, let your heart burn with loving kindness for all who may cross your path.

(`Abdu'l-Baha:  Paris Talks*, Page: 16)
