What Is a Mantra?

According to His Holiness the Jongdosanim of Jeung San Do,
“A mantra is a holy instrument that connects my mind and body with the universe, allowing me to become one with the universe.
It is the language of God.”
When you repeatedly chant a mantra, the vibrations within the mantra connect you to the corresponding sacred energy of the universe, allowing you to absorb this energy.
The Sanskrit word mantra literally means "instrument of thought".
Thus, a mantra can be considered to be a linguistic device for deepening one’s thought, or for developing the enlightened mind.
