English version: One should understand this standard accordingly. Next, it explains how this single syllable 'Hūṃ' encompasses the principles elucidated in various scriptures and treatises. The teachings of the *Mahavairocana Sutra* (Dainichi-kyō) and the *Vajrasekhara Sutra* (Kongōchō-kyō) do not go beyond the three phrases: Bodhi as the cause, great compassion as the root, and skillful means as the ultimate. If one condenses the extensive into the concise, and returns the end to the origin, then all teachings are inseparable from these three phrases. These three phrases are bound into a single syllable 'Hūṃ', vast without confusion, concise without omission. This is accomplished by the natural empowerment of the inconceivable power of the Tathagata. Even thousands of scriptures and ten thousands of treatises do not exceed these three phrases and one syllable. The cause, practice, and result revealed within that one syllable can be contemplated in accordance with the foregoing. It is not only the syllable 'Hūṃ' that embodies such meaning; each of the remaining seed-syllables (字門, jimon) is also like this. Secondly, the meaning of protection is: above there is a great void point, which is the syllable 'Kha' (佉字門, Kha-jimon) (representing emptiness). This is the meaning of great emptiness, which is also the meaning of the Prajñāpāramitā Buddha-mother (般若佛母, Hannya Butsumo) and consort. In the middle there is the syllable 'Ha' (诃字, Ka-ji), which is the meaning of cause. Within this treasury of emptiness, it contains and nourishes the seed of true cause, which is the meaning of great protection. Again, the meaning of freedom and the ability to destroy is: above there is a void point, which is the syllable 'Kha'. The syllable 'Kha' is like space, ultimately pure, without anything, which is the realm known by the Peak Observation (高峰觀, Kohōkan). In the middle there is the syllable 'Ha', which is the Bodhi banner, and also the power of freedom. Because these two syllables correspond, it is like a great general who can destroy enemies, so it is called the meaning of freedom and the ability to destroy. Again, the meaning of fulfilling wishes is: the syllable 'Ha' is the treasure of the Bodhi mind, and it combines with the treasury of emptiness of the syllable 'Kha', thus achieving the skillful-colored Mani (巧色摩尼, Kōshikimōni) (wish-fulfilling jewel), which can fulfill the hopes and wishes of all sentient beings, this is called the meaning of fulfilling wishes. Again, the meaning of great power is: the syllable 'Ha' Bodhi mind is complete with all the ten powers of the Tathagata, etc. Now, combined with the syllable 'Kha', it is free from all bonds and has no attachments or obstacles, like the wind in space rotating freely, so it is called great power. This great solid power originally comes from the Vajra nature of all Buddhas. Moreover, since countless kalpas, it has always fully cultivated the Dharma practice with this syllable 'Ha' as the true cause, and each of the ten thousand virtues of the syllable 'Kha' is like Vajra, indestructible, this is called the meaning of great power. Again, the meaning of terror is: this syllable 'Hūṃ' is the truthful word of all Tathagatas, so-called all dharmas are without --------------------------------------------------------------------------------

因无果本来清净圆寂义。是故才发菩提心。即坐菩提道场转正法轮。由此相应故能证悟一切佛法。念念具萨般若智。直至究竟坐金刚座。四魔现前则入大慈三摩地。恐怖降伏四魔等。所谓四魔者蕴魔烦恼魔死魔天魔。如是魔军无不恐怖降伏。犹如日轮才举暗暝消退。复次如来以何法恐怖诸障耶。谓即以此吽字门也。下三昧画即是具修万行。上有大空点即是已成万德。诃字即是法幢旗。三昧空点合故即是高峰观三昧。上点是明妃之母。下画是胎分日增。如是义故适发声时魔军散坏。即是恐怖义也。复次等观欢喜义者。此吽字中有诃字是欢喜义。上有大空是三昧耶。下有三昧画字是亦三昧耶。二三昧耶中行。三世诸佛皆同此观。故名等观义 现代汉语译本：因为没有果，本来就是清净圆寂的意义。所以才发起菩提心（bodhicitta，觉悟之心），随即在菩提道场（bodhimanda，觉悟之地）转动正法轮（dharma wheel，佛法之轮）。由此相应，所以能够证悟一切佛法。每一个念头都具备萨般若智（sarvajna-jnana，一切智智），直至最终安坐于金刚座（vajrasana，金刚座）。四魔（catuh-mara，四种魔障）现前时，则进入大慈三摩地（maha-maitri-samadhi，伟大的慈悲禅定）。以恐怖降伏四魔等。所谓的四魔是：蕴魔（skandha-mara，五蕴之魔）、烦恼魔（klesa-mara，烦恼之魔）、死魔（mrtyu-mara，死亡之魔）、天魔（deva-mara，天神之魔）。像这样的魔军没有不恐怖降伏的，犹如太阳一升起，黑暗就消退。再次，如来（tathagata，佛）以什么法来恐怖诸障呢？就是用这个吽（hum，种子字）字门。下面的三昧画就是具足修习万行，上面有大空点就是已经成就万德。诃（ha，种子字）字就是法幢旗。三昧空点合在一起就是高峰观三昧。上面的点是明妃之母，下面的画是胎分日渐增长。因为这样的意义，所以当发出声音时，魔军就溃散破坏，这就是恐怖的意义。再次，等观欢喜的意义是：这个吽字中有诃字，是欢喜的意义。上面有大空是三昧耶（samaya，誓言），下面有三昧画字也是三昧耶。在二三昧耶中修行，三世诸佛都同样如此观想，所以名叫等观义。

English version: Because there is no result, it is originally the meaning of pure nirvana. Therefore, the bodhicitta (bodhicitta, the mind of enlightenment) is aroused, and then the dharma wheel (dharma wheel, the wheel of Dharma) is turned in the bodhimanda (bodhimanda, the place of enlightenment). Correspondingly, one can realize all the Buddha-dharma. Every thought is endowed with sarvajna-jnana (sarvajna-jnana, all-knowing wisdom), until finally sitting on the vajrasana (vajrasana, diamond throne). When the four maras (catuh-mara, four kinds of demonic obstacles) appear, one enters the maha-maitri-samadhi (maha-maitri-samadhi, great loving-kindness samadhi). Subduing the four maras with terror, etc. The so-called four maras are: skandha-mara (skandha-mara, the demon of the five aggregates), klesa-mara (klesa-mara, the demon of afflictions), mrtyu-mara (mrtyu-mara, the demon of death), and deva-mara (deva-mara, the demon of gods). Such a demonic army is invariably terrified and subdued, just as darkness disappears when the sun rises. Furthermore, by what Dharma does the Tathagata (tathagata, Buddha) terrify all obstacles? It is by this Hum (hum, seed syllable) syllable-gate. The samadhi drawing below is the complete practice of myriad actions, and the great void point above is the accomplishment of myriad virtues. The syllable Ha (ha, seed syllable) is the banner of the Dharma. The combination of the samadhi void point is the samadhi of the peak view. The point above is the mother of the vidya, and the drawing below is the daily increase of the fetal division. Because of this meaning, when the sound is uttered, the demonic army scatters and is destroyed, which is the meaning of terror. Furthermore, the meaning of equal contemplation and joy is: in this Hum syllable, there is the syllable Ha, which is the meaning of joy. Above is the great void, which is samaya (samaya, vow), and below is the samadhi drawing syllable, which is also samaya. Practicing in the two samayas, all Buddhas of the three times contemplate in the same way, hence it is called the meaning of equal contemplation. --------------------------------------------------------------------------------
