Orthodox worship is characterized by a complete utilization of the senses sight, smell, hearing, speech and touch. We see the candles, Icons, frescoes, etc., we hear the sounds of singing and reading, at times lifting up our own voices, and we smell the characteristic odor of the incense. The whole of the human person is involved in worship, and important among the senses is the actual deportment of the human body. The attitude of the Orthodox Believer to worship is reverential, and certain types of bodily movements are utilized to reinforce this sense of reverential piety we stand during the services, we make bows and prostrations, and with great frequency, we make the Sign of the Cross. Accordingly, there are several types of Bows, depending on the solemnity of the moment.
