How can I choose to sleep, O God, my God, when the eyes of them that long for Thee are wakeful because of their separation from Thee; and how can I lie down to rest whilst the souls of Thy lovers are sore vexed in their remoteness from Thy presence? I have committed, O my Lord, my spirit and my entire being into the right hand of Thy might and Thy protection, and I lay my head on my pillow through Thy power, and lift it up according to Thy will and Thy good-pleasure. Thou art, in truth, the Preserver, the Keeper, the Almighty, the Most Powerful. By Thy might! I ask not, whether sleeping or waking, but that which Thou dost desire. I am Thy servant and in Thy hands. Do Thou graciously aid me to do what will shed forth the fragrance of Thy good pleasure. This, truly, is my hope and the hope of them that enjoy near access to Thee. Praised be Thou, O Lord of the worlds!
(Bahá’u’lláh, Prayers and Meditations by Bahá’u’lláh, p. 263-264)
O my God, my Master, the Goal of my desire! This, Thy servant, seeketh to sleep in the shelter of Thy mercy, and to repose beneath the canopy of Thy grace, imploring Thy care and Thy protection. I beg of Thee, O my Lord, by Thine eye that sleepeth not, to guard mine eyes from beholding aught beside Thee. Strengthen, then, their vision that they may discern Thy signs, and behold the Horizon of Thy Revelation. Thou art He before the revelations of Whose omnipotence the quintessence of power hath trembled. No God is there but Thee, the Almighty, the All-Subduing, the Unconditioned.
(Bahá’u’lláh, Prayers and Meditations by Bahá’u’lláh, p. 262)
