The Five Tibetan Rites of Rejuvenation were not designed as beginner yoga, nor are they, but the fact they only take twenty minutes or so makes them totally accessible to our busied mind and active lifestyle that prevents us beginner yogis from beginning. I have arranged some finer points of each in the following.
There are 5 movements done 21 times and 1 movement done, most frequently, 3 times, equating to 108 breath coordinated movements. Each of the Tibetans are followed by taking two breaths so as to balance out the energy just moved. The Sixth Tibetan is only performed after you are capable of doing 21 breath coordinated movements of the Five Tibetans and doesn't have to be included otherwise. One can begin doing any number of each Rite that you feel comfortable with, but try to do an equal number of each.
The First Tibetan is simply spinning clockwise with the arms active to the sides. The first Rite is done clockwise in unison with the sun for the chakras are said to spin clockwise. When held up such activates and opens up the arms, shoulders and neck. Try going excruciatingly slow. The Five Rites strengthen and activate the abdominal area and neck. These areas are considered the most problematic and clogged in terms of energetic and chakra understandings too. The Rites open up the chakras.
Then take two breaths like Superman, that which devoted practice can turn you into. Hands are at your hips. Take a deep breath through your nose and exhale through your mouth with lips shaped in an O like Superman blowing out cold air.
The trick to the second Tibetan is to lift up and set down the legs and neck in unison. Each Tibetan is done in unison with the breath and as with all meditative movement, the inhale is tension/activation and exhale is relaxation/release. So each movement begins with inhale and returns with exhale. The easiest way to count is to count 1 on the inhale and 1 on the exhale, counting each twice so you are less likely to lose track.
A trick with the third Tibetan is to think about using your hands as support and about bringing bring your back so that it returns to being perpendicular or just slightly past perpendicular, a degree or two forward. Go slow.
The trick to the fourth Tibetan is to initiate the movement with your neck opening the throat chakra.
As you progress you will eventually be able to do the fifth Tibetan with opened joints and ligaments doing Hindi pushups where your face glides along just above the floor and then rises up, like a cobra, on the return/release.
Remember to breathe twice like Superman in between each Rite.
The trick with the sixth Tibetan is to not do it unless you can do 21 of each of the first Five. I find three of the sixth Tibetan is optimal and no more than five is advised.
