Repetition of Hari Om forms a type of meditation in itself, referred to simply as Hari Om meditation. To meditate on Hari Om is said to activate the chakras. In doing so, kundalini energy, which is stored at the base of the spine, can move upward through the nadis. Hari Om meditation also allows prana to move from one energy center to the next.
Some say that the Hari Om mantra is a shortened version of the mantra, Hari Om Tat Sat. Om Tat Sat can be considered as three words for God, and translated as “Supreme Absolute Truth” or “all that is.” Hari prefaces this mantra as it is the name of God in the physical form. This is said to allow the speaker of the mantra to explore the sat, or the truth, from their physical form.
Hari Om meditation is reputed to be particularly helpful for those suffering from depression as it improves the mental condition, finding happiness through one's connection with the universal energy.
