Modes of Transmissions
They have been transmitted down to the present day in three distinctive phases: the lineage of the enlightened intention of the conquerors, the lineage of the symbolic gestures of the awareness holders, and the lineage of aural transmission through exalted individuals.
The lineages of the three inner classes of tantra – Mahayoga, Anuyoga and Atiyoga – all derive ultimately from Samantabhadra – the primordial buddha-body of reality, the fundamental nature or actual reality of buddha-mind.
the realization of manifestly perfect buddhahood upon the five buddhas (Vairocana and so forth) who preside over the assembly of the hundred peaceful and wrathful deities, and who assume the buddha-body of perfect resource, inseparable from himself.
Simultaneously, in a special realm of Akanistha, the same blessing is conferred by the peaceful aspects of buddha-body of perfect resource – Vairocana and so forth – through symbolic gestures indicative of enlightened intention,
upon the most exalted bodhisattvas – Vajrapani, Avalokiteshvara and Manjughosa, each of whom is responsible for communicating these teachings symbolically to their respective followers – yaksas, nagas and devas.
Meanwhile, in lesser realms of Akanistha the wrathful aspects of the buddha-body of perfect resource confer the same blessing through the imperishable sound of pure vibration upon harmful beings – Rudra, Bhairava and so forth; and, in a lower realm known as the Abode of the Thirty-three Gods (Trayatrimsha),
These transmissions, whereby the teachings of the buddha-body of perfect resource are conferred on the buddha-body of emanation, are collectively known as the lineages of the symbolic gestures of the awareness-holders, and are therefore devoid of verbal expressions.
King Indrabhuti assumed the name Vyakaranavajra and, as such, he received the Anuyoga tantras from the aforementioned Vimalakirti, transmitting them in turn through Kambalapada, Prahevajra, Shakyaprabha (Prabhahasti), Shakyasimha (Padmasambhava), Dharanraksita, and Dharmabodhi.
The Atiyoga tantras are said to have been transmitted by Prahevajra through Manjushrmitra, who divided them into three classes, and Sri Simha who divided the pith instructions into four teaching-cycles.
This includes those treasure finders who discover their appropriate revelations on the basis of the former enlightened aspirations of Padmasambhava and Yeshe Tsogyal (ye shes mtsho rgyal) that the indicated individuals will emerge in the future to reveal their respective treasures.
Finally, the [[lineage of the dakinis’ seal of entrustment]] includes those treasure-finders to whom the guardians of the treasures rightfully bequeath encoded texts, which they alone are able to interpret.
