I wrote recently about how the Accessing the Knowledge of the Universe is one of my new favorite meditations. In it you hold the lotus mudra whisper the Pavan Pavan mantra for 31 minutes. There is something special about whispering and it’s subtle affect on your ethereal fields.
In some ways I like whispering more than chanting at full volume because of it’s elegance. I find that after a fairly short time period I am able to fold my consciousness into the current of sound and leave my body and energy lightly vibrating. Love it!
