Om Ah Hung mantra recitation
HE 8th Garchen Rinpoche:
"Now regarding the OṀ ĀH HUṂ practice, there are different visualizations and ways of focusing the mind that can be practiced. For example, in the context of other practices like when we extract essences, or when we receiving siddhis or empowerments and so on, all of these practices essentially are just a method for having the mind abide single pointedly, as is the OṀ ĀH HUṂ.
One way of practicing the OṀ ĀH HUṂ is that when you inhale, on the inhalation you think OṀ. The wind goes down to the navel where you think ĀH and then you hold it there for as long as you can. Then with HUṂ you exhale, but what you’re actually exhaling is just half of the wind and the stale air and the actual wind, which is the HUṂ. Then, this stays in the navel dissolving into the navel. So then you can just practice a kind of a gentle retaining of the winds.
At the end of your session, when you arise from your session you can now say a shorter, or a faster OṀ ĀH HUṂ, and then you stabilize your awareness in the OṀ ĀH HUṂ. Then you go about your day-to-day activities and then in all your activitie, because you’re breathing together with your natural breath, you continue to sustain awareness of the OṀ ĀH HUṂ all the time.
Then also at night, when you go to sleep, lie down on your right side and until you fall asleep into a state of unconsciousness also practice the OṀ ĀH HUṂ vajra recitation. If you fall asleep with this awareness it is said that then the entire sleep time becomes actually the virtue of mantra recitation. Then also eventually as you’re sleeping and dreaming, the OṀ ĀH HUṂ will come to your dream and when you recognize it there, this is called the subtle luminosity. so the there’s the subtle luminosity and the deep luminosity or the deep sleep luminosity. That can be also practiced just through the OṀ ĀH HUṂ vajra recitation. First, in the dream state the imprint of virtue arises and then you come to the actual nature the view, or the natural state of the mind, and then you recognize the dream state. There is an instruction that is called the instruction of recognizing the luminosity of the dream state. That is very much connected to the OṀ ĀH HUṂ vajra recitation."
