"Bestir yourselves, that the brief moments that are still yours may not be dissipated and lost."

"Night hath succeeded day, and day hath succeeded night, and the hours and moments of your lives have come and gone, and yet none of you hath, for one instant, consented to detach himself from that which perisheth. Bestir yourselves, that the brief moments that are still yours may not be dissipated and lost. Even as the swiftness of lightning your days shall pass, and your bodies shall be laid to rest beneath a canopy of dust. What can ye then achieve? How can ye atone for your past failure?"

-Bahá'u'lláh, Gleanings From the Writings of Bahá’u’lláh, p. 321
