谓乐为空点。由业之风所策动，于脐之坛城中燃。由得乐而知足，入定而安住。勇士吉祥黑汝嘎，此谓乐与空点。如是，以乐之空点略示与广释二者所说，乃拙火瑜伽之根本。其中前四句，显示中脉，其亦于心间脉瓣之莲花内或中央生起，是为处所。颜色：于拙火燃烧之时，如麻油灯之体性般，具光芒之自性，形状：如水树之花，稍稍张开，于脉结之内生起之瓣，观待而置之口则向下伸展或垂下。其后四句，显示中脉内之字，以于中脉内安住，摧灭不顺之分别念故，勇士乃吽字。（藏文：ཧཱུྃ，梵文天城体：हुं，梵文罗马拟音：hūṃ，汉语字面意思：吽）。其量为芥子许。不坏者：为成办现欲之义，他人所不能摧毁者。此乃依于拙火而生乐之种子。如雪般具清凉光芒之甘露光芒滴落。此乃令有身者之安乐喜宴燃起故，称为乐，以其相似故如是称之。其后二句显示空点，譬如鹫母之火吞噬大海之无余水，如是焚烧蕴等之无余薪柴之脐火之形相，无我无所作，从一切中返回之空点。其由脐下之风所策动且增长，故于脐之坛城中燃烧。业：从拙火修习中所生之心之作用，乃由决定风策动之力量。注释中，业所策动之风所推动之谷物增补。乐，获得菩提心滴落而知足，即为生起满足之喜悦，为此二者交合，是为入定，此即乐与空点二者之谓，亦即婆散陀与帝拉嘎。其广释于交合中，于脐间以阿字之形相

It refers to bliss as bindu. Driven by the wind of karma, it burns in the mandala of the navel. Satisfied by obtaining bliss, it abides in samadhi. The hero Shri Heruka, this is called bliss and bindu. Thus, what is said by the two, the brief and extensive explanation of the bindu of bliss, is the root of the yoga of tummo. Among them, the first four lines show the central channel, which also arises in or in the center of the lotus of the heart channel petals, which is the place. Color: When tummo is burning, it is like the nature of a sesame oil lamp, with the nature of light, and the shape: like a water tree flower, slightly open, and the petals that arise inside the knot of the channel, with the mouth placed facing down or hanging down. The next four lines show the letter inside the central channel, because it abides in the central channel and destroys discordant thoughts, the hero is the letter Hum. (Tibetan: ཧཱུྃ, Sanskrit Devanagari: हुं, Sanskrit Roman transliteration: hūṃ, Chinese literal meaning: Hum). Its size is that of a mustard seed. The indestructible: to accomplish the meaning of manifest desire, which cannot be destroyed by others. This is the seed of happiness that arises from relying on tummo. Like snow, the nectar rays with cool light drip. This is called bliss because it ignites the joyful feast of happiness for embodied beings, and it is named so because it is similar to it. The next two lines show the bindu, for example, the fire of a vulture mother devours all the water of the ocean, just like the form of the navel fire that burns all the firewood such as aggregates, the bindu that is selfless and uncreated, and returns from everything. It is moved and increased by the wind below the navel, so it burns in the mandala of the navel. Karma: the action of the mind arising from the practice of tummo, which is the power of the determined wind. In the commentary, the grain is supplemented by the wind driven by karma. Bliss, obtaining the dripping of bodhicitta and being satisfied, that is, generating the joy of satisfaction, for this the union of the two is samadhi, which is called both bliss and bindu, that is, vasanta and tilaka. Its extensive explanation is in union, in the navel with the form of the letter A.
