脐轮等轮的中心，首先进入，中间住留，最后融化。融化之时，细微和粗大的脉依次融化的方式，以及特殊的融化乐会产生很多，这也是大乐的因。第二是手印等，这有事业手印和它的支分。第一是： 手印的命勤，如同依靠上方的命勤，风依次进入、住留、融于中脉一样，与手印一同修习，也会到达成为命勤的时候。由于手印的缘故，进入、住留、融于中脉同时发生，能迅速引导菩提心降临于中脉的寂静大乐。以触及自身要处的四喜，粗略地、尽可能地表示乐、空、自性、显现的差别，但要详细和完整地表示，则依赖于事业手印。同样，触及自身不同的部位，会显现不同的智慧形象。如同它们每一个都有不同的证悟方式一样，事业手印的种类不同也有差别。然而，这是能否完整引导四显和四喜智慧的差别。事业手印中最殊胜的是三处空行母，三处分为二十四个处所，获得它们的特殊聚合，通常能迅速赐予两种成就，特别是能解开七万二千根脉的脉结，能止息二十四种风的转移，能使二十四种垢染和清净物转换位置。这样，依靠清净所依的能力，所依的乐空无二智慧，能从无有波涛的广大中生起。虽然其他的次第事业手印也能做到，但因为这个能迅速做到，所以才说是事业手印中最殊胜的。第二是：为了使智慧稳固，意手印，也叫智慧手印。显现为以分别念修习的手印，无分别念而显现的是自显的明妃或者有相大印。

The center of the navel chakra and other chakras, first enters, stays in the middle, and finally dissolves. At the time of dissolution, the way the subtle and coarse channels dissolve in sequence, and many special melting pleasures will arise, which is also the cause of great bliss. The second is mudra, etc., which has karma mudra and its branches. The first is: The life force of the mudra, just as relying on the life force above, the wind enters, stays, and dissolves into the central channel in sequence, practicing together with the mudra will also reach the time of becoming the life force. Due to the mudra, entering, staying, and dissolving into the central channel occur simultaneously, which can quickly guide the bodhicitta to descend into the peaceful great bliss of the central channel. By touching the four joys of one's own body, the differences between bliss, emptiness, nature, and appearance can be roughly and as much as possible expressed, but to express them in detail and completely depends on the karma mudra. Similarly, touching different parts of one's own body will reveal different wisdom images. Just as each of them has a different way of realization, there are also differences in the types of karma mudra. However, this is the difference between whether or not one can completely guide the wisdom of the four appearances and the four joys. The most supreme of karma mudras is the three-place dakini. The three places are divided into twenty-four places, and obtaining their special aggregation can usually quickly bestow two kinds of achievements, especially to untie the knots of the 72,000 channels, to stop the transfer of the twenty-four winds, and to transform the twenty-four impurities and pure substances. In this way, relying on the power of the pure support, the wisdom of the support's bliss and emptiness being non-dual can arise from the vastness without waves. Although other sequential karma mudras can also do this, it is said to be the most supreme of karma mudras because it can do it quickly. The second is: in order to stabilize wisdom, the mind mudra, also called the wisdom mudra. Appearing as a mudra practiced with conceptual thoughts, what appears without conceptual thoughts is the self-appearing vidya or the form mudra.
