关于“ུ་”的解释分为两部分：广大续部的决定和甚深口诀的决定。第一部分分为两点：续部的体性和详细分类。第一点是作为基础、道、果的所说和能说存在，并与眷属一起。其中，基础续是自生智慧，任运成就，不可改变。道之续是凭借灌顶和诀窍证悟，以及越来越高的三摩地。证悟之续是从最初法性现前到未解脱于光明法界之间的智慧功德，如见和三摩地等。圣言是指如续部一样，作为修持之方便出现的名、词、字母显现，以及经卷等。第二，分类分为两种，如《珍珠鬘》中所说：“诶玛，金刚持谛听！彼之如是解释者，意义之续和词句之续。”因此，作为基础，遍及一切智慧之存在方式的是意义之续，而为了象征和修持它，以支分等方式，即在各个部类中显示的是词句之续。第一，意义之续。它的类别分为方便之续和自性之续两种。如彼（《珍珠鬘》）中所说：“秘密续之方便和，自性如何唯一上。”如是说。第一是象征法界之意义，作为示现者。分类为所象征的方便之续和能象征的方便之续两种。如彼（《珍珠鬘》）中所说：“基础一，自性之差别上，所象征和能象征。”如是说。其中，所说之意义的总相是所象征。它的存在方式的区分是能象征，指的是意义和名相。其中，自明光明遍一切处大者是所象征之续。如彼（《珍珠鬘》）中所说：“所象征续一，遍一切处故，一切皆随彼之后。”如是说。如何遍及呢？以法界空性本来清净法性和智慧显现任运成就大者无别的方式遍及。如彼（《珍珠鬘》）中所说：“遍及有两种，以空性遍及和以光明遍及。”如是说。能象征是成为证悟彼之方便者，大手印立断顿超和妥噶五光自显灯等本来具足。

The explanation of "u" is divided into two parts: the determination of the vast tantras and the determination of the profound oral instructions. The first part is divided into two points: the nature of the tantras and the detailed classification. The first point is that it exists as the subject and object of the ground, path, and fruition, together with the retinue. Among them, the ground tantra is self-born wisdom, spontaneously accomplished, and immutable. The path tantra is the realization through empowerment and instructions, and the attainment of increasingly higher samadhis. The realization tantra is the wisdom qualities from the initial manifestation of dharmata to the non-liberation into the clear light dharmadhatu, such as view and samadhi, etc. The agama refers to the appearance of names, words, and letters as a means of practice, as in the tantras, and the scriptures, etc. Secondly, the classification is divided into two types, as stated in the "String of Pearls": "Ema, Vajradhara, listen! That which is to be explained, the tantra of meaning and the tantra of words." Therefore, as the ground, that which pervades all the ways of being of wisdom is the tantra of meaning, and that which symbolizes and practices it, with its branches, i.e., shown in various categories, is the tantra of words. First, the tantra of meaning. Its categories are divided into two types: the tantra of means and the tantra of nature. As it says in that (the "String of Pearls"): "The means of the secret tantra and, how the nature is one." Thus it says. The first is to symbolize the meaning of dharmadhatu, as the demonstrator. It is classified into two types: the tantra of means to be symbolized and the tantra of means that can symbolize. As it says in that (the "String of Pearls"): "One ground, on the difference of nature, the symbolized and the symbolizer." Thus it says. Among them, the general aspect of the meaning to be expressed is the symbolized. The distinction of its mode of existence is the symbolizer, which refers to meaning and nomenclature. Among them, self-awareness, clear light, all-pervading greatness is the tantra of the symbolized. As it says in that (the "String of Pearls"): "The symbolized tantra is one, because it pervades all, all follow after it." Thus it says. How does it pervade? It pervades in an inseparable way with the dharmadhatu emptiness, primordial purity dharmata, and the wisdom appearance spontaneously accomplished greatness. As it says in that (the "String of Pearls"): "There are two types of pervasion, pervasion by emptiness and pervasion by clarity." Thus it says. The symbolizer is that which becomes the means to realize it, the great Atiyoga Trekchö and Tögal, the five lights, self-appearing lamps, etc., are inherently present.
