A thankful person is thankful under all circumstances. A complaining soul complains even in paradise.
Bahá'u'lláhSpeak no evil, that thou mayest not hear it spoken unto thee, and magnify not the faults of others that thine own faults may not appear great.
Bahá'u'lláhBe generous in prosperity and thankful in adversity, Be fair in thy judgment, and guarded in thy speech. Be a lamp unto those who walk in darkness, and a home to the stranger. Be eyes to the blind, and a guiding light unto the feet of the erring. Be a breath of life to the body of humankind, a dew to the soil of the human heart, and a fruit upon the tree of humility.
Bahá'u'lláh
