Om. Its meaning lies within the soul. The self within. It refers to Atman and Braham; the ultimate reality, entirety of the universe, the supreme spirits and the cosmic principles. It is the most highest sacred symbol in the Hindu religion. These two letters alone are so extremely powerful and symbolic that the world alone can bring such immense change and positivity in your life. It can make you feel so extraordinary that it allows you to touch each corner of the universe and spiritually connect with it.
