The power of mantra is multifold: first we are activating the 84 meridians via the upper palate to create vibration, which carries information. This vibration shifts the neurochemical release in the body which shifts your electromagnetic field.
Mantras are typically in Gurmukhi, a sacred Indian language, and occasionally, in English. These mantras contain the vibrations of peace, prosperity, connection, and many other qualities understood by their impact, even if the meaning of each word is not known. Pronunciation comes with repetition and by example. Many mantras are available to listen to on the KRI website.
Understanding the meaning of the words adds another layer of effectiveness to chanting.
The first mantra chanted at the beginning of every kundalini yoga class is the Adi Mantra followed by A Mangala Charan Mantra.
ONG NAMO GURU DEV NAMO (the Adi Mantra)
I bow to the Creative Wisdom, I bow to the Divine Teacher within.
AD GURAY NAMEH, JUGAAD GURAY NAMEH, SAT GURAH NAMEH, SIREE GUROO DAYV-AY NAMEH (a mangala charan mantra) This mantra protects the body in light so the heart is free to open.
This mantra is used for “tuning in” to the divine flow and self-knowledge within each of us, and linking us to Yogi Bhajan and the Golden Chain of teachers. It is chanted at least three times at the start of each Kundalini Yoga class.
