"Strive, O people, to gain admittance into this vast Immensity for which God ordained neither beginning nor end, in which His voice hath been raised, and over which have been wafted the sweet savors of holiness and glory. Divest not yourselves of the Robe of grandeur, neither suffer your hearts to be deprived of remembering your Lord, nor your ears of hearkening unto the sweet melodies of His wondrous, His sublime, His all-compelling, His clear, and most eloquent voice."

-Bahá'u'lláh, Gleanings From the Writings of Bahá’u’lláh,  LII, p. 107
