A CD-ROM is an acronym for Compact Disk – Read Only Memory. It is a CD that is played in the CD drive of your computer. In Ocean Psalms, the CD contains text, graphics, images, sound and video. It cannot be played in an audio CD player. It is not a DVD so can not be played on a DVD player linked to your TV. Once you put the Ocean Psalms CD-ROM in your computer or laptop CD drive, you are able to sit and watch, listen, read and meditate on one of the 31 segments in the four sections, Dawn, Midday, Evening and Dark. You can access the sections and segments through the main menu or the CD Map.
