Although Om symbolizes the most profound concepts of Hindu belief, it is in use daily. The Hindus begin their day or any work or a journey by uttering Om. The sacred symbol is often found at the head of letters, at the beginning of examination papers and so on. Many Hindus, as an expression of spiritual perfection, wear the sign of Om as a pendant. This symbol is enshrined in every Hindu temple premise or in some form or another on family shrines.
