"Whosoever wisheth, let him turn thereunto; whosoever wisheth, let him turn away."

"O the pity! that man should deprive himself of this goodly gift, this imperishable bounty, this everlasting life. It behooveth him to prize this food that cometh from heaven, that perchance, through the wondrous favours of the Sun of Truth, the dead may be brought to life, and withered souls be quickened by the infinite Spirit. Make haste, O my brother, that while there is yet time our lips may taste of the immortal draught, for the breeze of life, now blowing from the city of the Well-Beloved, cannot last, and the streaming river of holy utterance must needs be stilled, and the portals of the Riḍván cannot for ever remain open. The day will surely come when the Nightingale of Paradise will have winged its flight away from its earthly abode unto its heavenly nest. Then will its melody be heard no more, and the beauty of the rose cease to shine. Seize the time, therefore, ere the glory of the divine springtime hath spent itself, and the Bird of Eternity ceased to warble its melody, that thy inner hearing may not be deprived of hearkening unto its call. This is My counsel unto thee and unto the beloved of God. Whosoever wisheth, let him turn thereunto; whosoever wisheth, let him turn away. God, verily, is independent of him and of that which he may see and witness."
