"Soham" means "He I am" or "I am He", "I am Brahman." "Sah" means "He (supreme being)." "Aham" means "I." This is the greatest of all Mantras
Therefore, the translation of So Hum is “I Am That.” Many Vedic scholars have interpreted the “That” in the mantra to represent the Universe, and it is now widely understood that the So Hum mantra symbolizes the fact that we are all connected to the universal energy that is constantly supporting and nourishing us in the ways we need and desire. It falls into the same concept as “oneness,” or “I am one with the Universe and all of creation.”
If you concentrate on the breath you will notice that the breath is gradually becoming very, very slow when concentration becomes deep. Gradually the repetition of Soham will drop when there is deep concentration. The mind will become very calm. You will enjoy. Ultimately you will become one with the Supreme Self.
