CHAPTER FIVE
The entering, the remaining, and the dissolving process in the Central Channel:
THE ART OF GTUM-MO OR HEAT YOGA
Through the above-mentioned three practices, prana will enter into the Central Channel, but in this connection one may ask what are the unmistakable signs of the prana entering into the Central Channel? (In other words, what are the right signs one should expect to experience if the pranas are on the point of entering into the Central Channel?) This is an extremely important question; there is a great number of different answers. Among them the definite and unmistakable sign is the following experience. After the meditation period, the yogi identifies the particular nostril from which the breathing (or most of the exhaled air) runs. Then he applies the mental and bodily practices as before. In a very short time, the breath running through both nostrils becomes even, and it should not alter within one or two breaths. If there is no other hindrance, the breath should remain even in both nostrils; the strength of both nostrils should be equal. If the yogi is able to do this, he may be considered as having a little strength in leading the prana into the Central Channel. However, this does not mean that, by doing this practice once (attaining even runs of the breath in the two nostrils), the ordinary breathing-process, which unequally stresses the two nostrils, will be forever stopped.
Having learned how to make the prana enter into the
[paragraph continues] Central Channel, the yogi is taught the practice involving the prana remaining there.
In accordance with the teachings, the yogi carries on his practice and carefully observes the manner of the breath running in the nostrils. Gradually the breath will become more and more subtle, and finally it will stop. The Jetsun Milarepa said:
"Happy is the entering into the Central Channel by the air of Ro-ma and Rleyang-ma!
Happy is the cessation of the outgoing and ingoing breathing!
"Happy is the vast experience of the cessation of breath!"
As to the subtle breathing, for some it is difficult and for some it is easy. If the yogi finds it difficult to absorb the air, lie will in a few minutes feel it filling up his entire belly, but then it begins to dissolve. Immediately after the dissolving, he will feel an extraordinary warmness taking place in the fire-place of the Navel Center and Secret Center; thereafter, the Melting Bliss will take place.
