The Act of Prayer

Praying has many different forms.

• Prayer may be done privately and individually, or it may be done corporately in the presence of fellow believers.
• Some outward acts that sometimes accompany prayer are: ringing a bell; burning incense or paper; lighting a candle or candles; facing a specific direction (i.e. towards Mecca or the East); making the sign of the cross.
• A variety of body postures may be assumed, often with specific meaning (mainly respect or adoration) associated with them: standing; sitting; kneeling; prostrate on the floor; eyes opened; eyes closed; hands folded or clasped; hands upraised; and others. Prayers may be recited from memory, read from a book of prayers, or composed spontaneously as they are prayed. They may be said, chanted, or sung. They may be with musical accompaniment or not. There may be a time of outward silence while prayers are offered mentally. Often, there are prayers to fit specific occasions, such as the blessing of a meal, the birth or death of a loved one, other significant events in the life of a believer, or days of the year that have special religious significance. Details corresponding to specific traditions are outlined below.
