Brass OM symbol.
The Om sign has a significant meaning in Hinduism. It is believed that at the start of time when the universe was still void, there was only the sacred sound of Om, and that all the material in the word unfolded from the energy of this sacred sound. It is also believed that the three parts of this sound (the beginning, middle, and end), represent the creation, sustaining, and regeneration of the universe.
