What follows is my provisional translation (in other words, not official or authorized; see here for more) of a prayer from ʻAbduʼl-Bahá, the original text of which is published in Ḥaḍrat-i-ʻAbduʼl-Bahá: Majmúʻiy-i-Munáját-há, p. 39 (passage no. 38).
He is God
O Thou kind Lord! Sever this heart from all attachments, and with every one of Thy joyful tidings bestow gladness upon this soul. Free me from the fetters of friend and stranger alike, and captivate me with Thy love, that thereby I may grow completely crazed and maddened for Thee, such that I may neither desire nor seek aught else but Thee; that I may search for no other path but Thine, and refrain from uttering aught else but Thy mystery; and that, even as the bird of dawn, I may be held captive in the snare of Thy love, and lift up day and night, fervently and tearfully, the cry of “Yá Bahá’u’l-Abhá!”
