Why do we chant the OM mantra at the beginning and end of a Yoga class?
Everything in the universe is pulsating and vibrating, nothing is really standing still. The sound OM, when chanted, vibrates at the frequency of 432 Hz, which is the same vibrational frequency found throughout everything in nature. As such OM is the basic sound of the universe. By chanting it we are symbolically and physically tuning in to that sound and acknowledge our connection to all other living beings, nature and the universe.
In addition the vibrations also have a physical affect on the body by slowing down the nervous system and calming the mind.
It is also a way to set aside the time for our practice from the rest of our day and to signify that this is a special time in which we care for ourselves and practice being mindful, connecting us to our practice in a deeper way than just with physical postures.
