I'd like to share this mantra with you. It was taught to me by a rather excentric woman who has studied with many different spiritual groups in her life time. If I remember correctly, this one is used by Tibetian Monks. Repeat it over and over aloud and watch how your energy flows! I would be interested to hear what you feel after doing this mantra. I find it very refreshing to my entire being. It goes like this:

This energy sea;
This flowing key;
From the top of my head;
To the bottoms of my feet.

The full Tibetan Dumo Heat meditation is as follows:

This energy sea, this Tan T'ien, from below the navel to the soles of the feet, full of my Original Face; where are the nostrils on that face?

This energy sea, this Tan T'ien, from below the navel to the soles of the feet, full of my True Home; what need of a message from that home?

This energy sea, this Tan T'ien, from below the navel to the soles of the feet, full of the Pure Land of Consciousness only; what need of outer pomp for this Pure Land?

This energy sea, this Tan T'ien, from below the navel to the soles of the feet, full of the Amida Buddha of heart and body; what sermon would this Amida be preaching?
