A cessation of the subtle running breath will tend to accumulate the subtle distractions, whence great distractions often occur. In this connection those who do not know how to concentrate on the central point of the Wheels, and who engage themselves in various kinds of Vase-Breathing exercises, will neither help the prana to enter nor remain inside [the Central Channel], because these practices can not tame the pranas and make them gather in the Central Channel. Consequently, neither the entering into nor the remaining in the Central Channel will come to pass; therefore, one must discriminate carefully.

As to the length or the duration of holding the Vase-Breathing, the Dom Jun Tantra says:

"Knowing the way of practicing Vase Breathing as instructed before,
The yogi then sits in a lotus posture.
One hand rubs the other three times,
And then he snaps his fingers six times.
The duration of thirty-six snappings
Is the length of time of Vase Breathing.
The best are (able to hold on) three times as long;
The length of more than one hundred snappings."

The left hand is supinely placed on the knee and is rubbed by the right hand three times; then six snaps are made with the fingers. This is one complete process. If one is able to hold the breath for 108 times of such duration, it is the best; to hold seventy-two times is the medium, and thirty-six times is the minimum. It is also said that whoever holds the breath for any of these three durations will be able to conquer death.

Now, the second:

The manner of the Arising of the Four Blisses through the Prana Entering into the Central Channel.

Of this, three expositions are given:

1. The appearance of the signs.

2. The manner of the firing of Dumo

3. The melting of the Bodhi-Heart.

The manner of the arising of the Four Blisses that are produced by the melting of the Bodhi-Heart will be discussed, and also the practice on the meditation of the Innate-Born-Wisdom. Now, the first: Through concentration on the central point of the Navel Center, the live prana enters into the Central Channel, whereupon signs will appear. These signs are explained by the accomplished Yogi Lawaba:

"The first sign is like the bewildered animals.
The second sign is the smoke.
The third sign is like the light of the firefly.
The fourth sign is like the lamplight.
The fifth sign is without any form,
It appears like the clear firmament without any clouds."
