Here’s a prayer worth meditating on from Thomas à Kempis’ Imitation of Christ:

O thou light perpetual, passing all lights created, cast thou from above lightning, piercing all the inwards of my heart. Purify, make glad, quicken and clarify my spirit with its powers to cleave to thee in jubilant excess. O when shall that blessed and desirable hour come when thou wilt fill me with thy presence and thou shalt be all in all. As long as this is not given, there shall be no full joy.
