In all matters moderation is desirable. If a thing is carried to excess, it will prove a source of evil.
Bahá'u'lláhKnow thou that every fixed star hath its own planets, and every planet its own creatures, whose number no man can compute.
Bahá'u'lláhO SON OF MAN! I loved thy creation, hence I created thee. Wherefore, do thou love Me, that I may name thy name and fill thy soul with the spirit of life.
Bahá'u'lláhBeautify your tongues, O people, with truthfulness, and adorn your souls with the ornament of honesty. Beware, O people, that ye deal not treacherously with any one.
Bahá'u'lláhKnow verily that the purpose underlying all these symbolic terms and abstruse allusions, which emanate from the revealers of Gods holy cause, hath been to test and prove the peoples of the world; that thereby the earth of the pure and illuminated hearts may be known from the perishable and barren soil.
Bahá'u'lláh
