Prayer is a form of religious practice that seeks to activate a volitional connection to some greater power in the universe through deliberate intentional practice. Prayer may be either individual or communal and take place in public or in private. It may involve the use of words, song, or complete silence. When language is used, prayer may take the form of a hymn, incantation, formal creedal statement. There are different forms of prayer such as petitionary prayer, prayers of supplication, thanksgiving, and worship/praise. Prayer may be directed towards a deity, spirit, deceased person, for the purpose of worshiping, requesting guidance, requesting assistance, confessing sins or to express one's thoughts and emotions. Thus, people pray for many reasons such as personal benefit or for the sake of
others.
