Embracing Style: Inhale air sharply through the nostrils, then tighten the lower air, holding the two airs mixed in the abdomen. Swallow the air in the mouth and hold it as long as possible. If you feel uncomfortable, you can relax slightly, and finally exhale slowly. The fourth is the Rigid Style: Exhale as much air as possible and hold your breath. Second, learning the visualization of fire, there are four types: the condensed Tumo, the intermediate, the extensive, and the reverse. First, meditate on Tumo at the navel, and meditate on Brahma's fire below the navel. First, after completing all the preliminaries, simply visualize yourself as the deity. In the empty navel within the body, visualize an eight-petaled lotus, with the eight letters ཨ་（Tibetan, Devanagari: अ, Romanized Sanskrit: a, meaning: none）, ཀ་（Tibetan, Devanagari: क, Romanized Sanskrit: ka, meaning: ka）, ཙ་（Tibetan, Devanagari: च, Romanized Sanskrit: ca, meaning: ca）, ཊ་（Tibetan, Devanagari: ट, Romanized Sanskrit: ṭa, meaning: ta）, ཏ་（Tibetan, Devanagari: त, Romanized Sanskrit: ta, meaning: ta）, པ་（Tibetan, Devanagari: प, Romanized Sanskrit: pa, meaning: pa）, ཡ་（Tibetan, Devanagari: य, Romanized Sanskrit: ya, meaning: ya）, ཤ་（Tibetan, Devanagari: श, Romanized Sanskrit: śa, meaning: sha） inscribed on the eight petals. Alternatively, do not inscribe the letters, but simply visualize the petals. In the center of the lotus, visualize a dharma origin the size of a thumb, with its root pointing downwards. Within it, visualize a red ཨ་（Tibetan, Devanagari: अ, Romanized Sanskrit: a, meaning: none） adorned with a head ornament, or a short ཨ་（Tibetan, Devanagari: अ, Romanized Sanskrit: a, meaning: none） adorned with a head ornament, and focus on it with one-pointed attention. The second method is to visualize the central channel in the middle of the body, about the thickness of an arrow shaft, with its upper end inserted into the crown chakra and its lower end inserted below the navel. The central channel below the navel, measured about two fingers' width from the navel, has a triangular shape like the tip of a vajra stake. In the empty center, visualize either a red-black ཀྵ་（Tibetan, Devanagari: क्ष, Romanized Sanskrit: kṣa, meaning: ksha） or ཀྵུཾ་（Tibetan, Devanagari: क्षुं, Romanized Sanskrit: kṣuṃ, meaning: kshum）, and focus on it with one-pointed attention. Both of these methods require the practice of vase breathing. Second, the intermediate method, which has two parts: the root and the branches. First, between the heart chakra and below the navel, visualize the central channel, about the thickness of an arrow shaft. The heart chakra is an eight-petaled wheel, blue in color, with the petals facing downwards. In the center of the heart chakra, visualize ཧཱུཾ་（Tibetan, Devanagari: हूँ, Romanized Sanskrit: hūṃ, meaning: Hum）. The navel chakra has sixty-four petals, red-yellow in color, with the petals facing upwards. In the center of the navel chakra, visualize a red-yellow ཨཾ་（Tibetan, Devanagari: अं, Romanized Sanskrit: aṃ, meaning: Am）, which has the nature of fire. By drawing in the air, when the ཨཾ་（Tibetan, Devanagari: अं, Romanized Sanskrit: aṃ, meaning: Am） ignites the Tumo fire, it touches the ཧཱུཾ་（Tibetan, Devanagari: हूँ, Romanized Sanskrit: hūṃ, meaning: Hum） in the heart chakra. Visualize the bodhicitta nectar dripping from the ཧཱུཾ་（Tibetan, Devanagari: हूँ, Romanized Sanskrit: hūṃ, meaning: Hum）, and focus single-mindedly on the burning and dripping. The second is that the crown chakra has thirty-two petals, white in color, with the head facing downwards. In the center, visualize ཧཾ་（Tibetan, Devanagari: हं, Romanized Sanskrit: haṃ, meaning: Ham）. The throat chakra has sixteen petals, red in color, and in the center, visualize ཨོཾ་（Tibetan, Devanagari: ओं, Romanized Sanskrit: oṃ, meaning: Om）, which has the nature of fire.

Clearly visualize the deity. Hold the breath in kumbhaka. From the Om (藏文：ཨོཾ，梵文天城体：ओ，梵文罗马拟音：oṃ，汉语字面意思：嗡) at the throat, the fire of tummo blazes. Touching the Ham (藏文：ཧཾ，梵文天城体：हं，梵文罗马拟音：haṃ，汉语字面意思：吽) at the crown of the head, visualize a stream of bodhicitta flowing down like rain from the Ham (藏文：ཧཾ，梵文天城体：हं，梵文罗马拟音：haṃ，汉语字面意思：吽). Focus single-pointedly on the blazing and dripping. Third, regarding increasing tummo, there are two: combining with the movement of bindus and combining with the movement of wind. The first is: just as tummo increases from the spring point, without doing separate blazing and dripping, the tummo rises up from within the central channel. It exits from opening the door of the crucial point between the eyebrows. Touching all the Buddhas of the ten directions, causing them all to dissolve into bodhicitta. Entering from the crown of the head together with the fire, touching the Ham (藏文：ཧཾ，梵文天城体：हं，梵文罗马拟音：haṃ，汉语字面意思：吽). Visualize a stream of bodhicitta flowing down from the Ham (藏文：ཧཾ，梵文天城体：हं，梵文罗马拟音：haṃ，汉语字面意思：吽), gently dissolving into the Am (藏文：ཨཾ，梵文天城体：अं，梵文罗马拟音：aṃ，汉语字面意思：阿) at the navel. Focus single-pointedly on the blazing and dripping. The second is: when the breath goes out, visualize the tummo blazing from the Am (藏文：ཨཾ，梵文天城体：अं，梵文罗马拟音：aṃ，汉语字面意思：阿) and touching the Ham (藏文：ཧཾ，梵文天城体：हं，梵文罗马拟音：haṃ，汉语字面意思：吽). When the breath comes in, visualize a stream of bodhicitta flowing down from the Ham (藏文：ཧཾ，梵文天城体：हं，梵文罗马拟音：haṃ，汉语字面意思：吽) and dissolving into the Am (藏文：ཨཾ，梵文天城体：अं，梵文罗马拟音：aṃ，汉语字面意思：阿). Fourth, learning reversal has two parts: the root and the branches. The first is: visualize a red-black bindu like an eye at the center of the heart chakra, and a red-black bindu like an eye at the center of the navel chakra. Hold the breath in kumbhaka forcefully. Visualize a very hot red-black ray of light blazing downwards from the red-black bindu at the heart, touching the bindu at the navel. From the bindu at the navel, a very cool red-black ray of light arises. When these two collide, the ray of light arising from the heart bindu becomes shorter. The ray of light arising from the navel bindu becomes longer. Finally, touching the heart bindu, a flame-like ray of light arises from it. The previous navel flame becomes shorter, and the heart flame becomes longer, and visualize touching the navel bindu. Do this repeatedly. The second is: the crown petals as before, and the throat petals as before. Visualize a red-white bindu at each of the two navels. From holding the breath in kumbhaka forcefully, the red part of the red-white bindu at the crown becomes a flame, extending and moving downwards, touching the red-white bindu at the throat. From that, the white part becomes a flame, these two

通过争斗，顶轮的脉变得越来越短，喉轮的脉变得越来越长。当触及顶轮的明点时，从中出现红色的火焰。当触及喉轮的明点时，也从中出现火焰等等，要长期地修习。在这些时候，气的要点是：当从心轮的明点和顶轮的明点火焰向下流动时，用气结合的力量向下压；当从脐轮的明点和喉轮的明点火焰向上升起时，用气的力量向上提。还有，在向外呼气又屏住呼吸的时候，当明点的光芒向下流动时，进行空压；当明点的火焰向上升起时，进行空提。第三，学习明点瑜伽，有明点总的修习，明点特别的修习，以及修习道的支分。第一，总的修习是：观想自己显现为本尊，在顶髻轮（顶轮）四脉瓣的中心，有一个绿色的明点，放射着五种光芒。从那上面，一心专注，使之产生清晰的显现。然后，在头顶的脉轮十六脉瓣的中心，观想一个白色或黑色的明点，放射着光芒，修习并获得清晰的显现。然后，在喉轮的脉轮十六脉瓣的中心，观想一个红色的明点，放射着光芒，修习并获得清晰的显现。然后，修习心轮的脉轮八脉瓣的中心明点：如果在喉轮修习白色，那么这里就修习黑色；如果在喉轮修习红色，那么这里就修习白色，并获得清晰的显现。然后，脐轮的脉轮，内圈四脉瓣，外圈八脉瓣，再外圈十二脉瓣，再外圈六十四脉瓣，在它的中心，观想一个黄色的明点，放射着五种光芒，修习并获得清晰的显现。然后，在密处的脉轮十六脉瓣的中心，观想一个蓝色的明点，放射着五种光芒，修习并获得清晰的显现。当对这六个都稍微习惯后，然后从头顶到密处之间的明点，依次向上观想；从密处到头顶之间的明点，依次向下修习。第二，特别的修习是：在密处放置物质。

Through combat, the pulse of the crown chakra becomes shorter, and the pulse of the throat chakra becomes longer. When touching the bindu of the crown chakra, a red flame arises from it. When touching the bindu of the throat chakra, flames also arise from it, and so on, practice for a long time. At these times, the key to the prana is: when the flame flows downward from the bindu of the heart chakra and the bindu of the crown chakra, press down with the force of prana union; when the flame rises upward from the bindu of the navel chakra and the bindu of the throat chakra, pull the force of prana upward. Also, when exhaling and holding the breath, when the rays of light from the bindu flow downward, perform empty pressing; when the flame from the bindu rises upward, perform empty pulling. Third, in learning bindu yoga, there is general practice of bindu, special practice of bindu, and practice of the limbs of the path. First, the general practice is: visualize oneself as the deity, in the center of the four-petaled chakra of the crown, there is a green bindu, radiating five lights. From that, focus the mind one-pointedly, and make it produce a clear appearance. Then, in the center of the sixteen-petaled chakra of the crown of the head, visualize a white or black bindu, radiating light, practice and obtain a clear appearance. Then, in the center of the sixteen-petaled chakra of the throat, visualize a red bindu, radiating light, practice and obtain a clear appearance. Then, the practice of the bindu in the center of the eight-petaled chakra of the heart: if white is practiced in the throat, then black is practiced here; if red is practiced in the throat, then white is practiced here, and obtain a clear appearance. Then, the chakra of the navel, the inner circle of four petals, the outer circle of eight petals, then the outer circle of twelve petals, then the outer circle of sixty-four petals, in its center, visualize a yellow bindu, radiating five lights, practice and obtain a clear appearance. Then, in the center of the sixteen-petaled chakra of the secret place, visualize a blue bindu, radiating five lights, practice and obtain a clear appearance. When one is slightly accustomed to all six of these, then visualize the bindus from the crown to the secret place in ascending order; practice the bindus from the secret place to the crown in descending order. Second, the special practice is: placing substances in the secret place.
