A prayer aid or study tool comprises first and second card members. The first card is wider, and includes spaced parallel slits of slightly larger width than the second card. The spacing of the slits is in an amount corresponding to regions on the second card. The second card is passed through the slits so as to be viewable in the window thereby defined. Topics or information provide on the second card are then viewable in discrete portions of the size of the window defined by the slots, while other portions of the second card can be blocked from view by the first card, to assist in focusing on topics. The first card may be provided with printing thereon to assist in the prayer or study, such as religious text, hymns, poetry, drawings/photos, or the like. The prayer aid is also suitably implemented on a computer or PDA.
