According to Dzogpa Chenpo sources, Prahevajra was born to a daughter of the king if Oddiyana, which was located, according to some scholars, somewhere around the Swat valley in the present-day Pakistan. Oddiyana was the most important source of esoteric Buddhist teachings, or tantras. It was a place of power and a land of dakinis, rich in natural treasures, forests and wild animals. In Oddiyana there was also a magificient temple called Deché Tsekpa (Heap of Joy) surrounded by 6,108 small temples. All were endowed with great prosperity.
Not far off, on an island covered by golden sand, a nun named Sudharma, the daughter of King Uparāja and Queen Alokabhasvati (One with Lights) of Oddiyana was in absorption in a simple grass hut with an attendant named Sukhasaravati (Joyous Heart). One night, the nun had a dream in which and immaculate man with a white complexion came and placed three times on her head a crystal vase adorned with five syllables, symbolizing the five Buddhas. The vase emanated beams of light, and she was able to see the three worlds clearly.
In the tenth month after the dream, a son adorned with many auspicious signs were born to the nun. This child was the rebirth of Adhichitta, a manifestation of Vajrasattva who appeared in the god’s realm to propagate Dzogpa Chenpo there. The nun was frightened and ashamed. “This fatherless son will be none other than an evil spirit!” she exclaimed, and she threw him into a pit of ashes, although the attendant, who was herself adorned with auspicious qualities, warned the nun that the son was an enlightened manifestation. At that moment wondrous sounds were heard and rays appeared. Three nights later the nun recovered the infant, who was unharmed. She realized that he was an enlightened manifestation, and she brought him home, wrapped him in a white silk cloth, and gave him a bath. At that moment, the dakinis and sages showered praise and offerings on the infant, and from the sky gods proclaimed:
O protector, Teacher, Blessed One,
The lord of the world, who reveals the true nature,
Be our powerful protector.
Vajra of the Sky, we pray to you.
When the child was seven years old, bursting with the energies of wisdom, he insisted that his mother allow him to go see the scholars so he could debate them about religious doctrine. When he had permisson, he rushed to his father, King Uparaja, and requested to meet the scholars. He debated with five hundred scholars, none of whom could defeat him. Unanimously they accepted him as an enlighened incarnation and took his feet upon their heads in the gesture of highest reverence. They gave the boy the name Prajnabhava (Wisdom Nature). The king was very happy and gave the child the name Prahevajra (Vajra of Supreme Joy). He was also called Vetalsukha and Rolang Thaldok (Blissful Zombie and Ash-colored Zombie), as he had been recovered from the ashes where he had been buried.
Then in the north, on the precipice of Mount Suryaprakasha (Very Sunny Mountain), in a grass hut, he remained in contemplation until he reached the age of thirty-two. He received the empowerments, instructions, and entrustment of the tantras of Dzogpa Chenpo in an instant frm Vajrasattva and attained the stage of “no more training”, Buddhahood. The earth shook seven times, various sounds were heard from the sky, and a rain of flowers fell.
When those victorious sounds were heard, a heretical king sent assassins to murder Prahevajra, but they could not harm him, for his body was immaterial like the rays of the sun. Therupon Prahevajra rose up into the sky, and the king and his subjects developed faith in him and became Buddhists.
At thirty-two, he went to Malaya. He stayed at the submit of the mountain for three years and transcribed the teachings of the Buddhas of the past and especially the 6,400,000 verses of Dzogpa Chenpo, which were present in Prahevajra’s memory, with the help of Dakinis Vajradhatu and Anantaguna. Then he placed the teachings teachings in the care of Khandro Ngönpar Jungwa and charged Dakini Semden to make offerings to the sacred scriptures.
With miraculous display, Prahevajra went to the great stupa situated in the Shitavana, the mysterious charnel ground. There he gave teachings to numerous disciples including the Dakini Suryakirana. During that time, in accordance with Manjushri’s prophetic advice, master Mañjuśrīmitra came to the Shitavana charnel ground and received the Nyingthig teachings from Prahevajra for seventy-five years.
According to Khandro Nyingthig and other sources, Shrisimha also came to Shitavana charnel ground and received Khandro Nyingthig and other teachings from Prahevajra, and later he transmitted them to Guru Padmasambhava and Vairochana.
At the end, at the source of the river Danatika, the mortal body of Prahevajra dissolved into immaculate space, amid wondrous signs of earth tremors, a great mass of rainbow light, and various sounds.
When Mañjuśrīmitra offered the prayers of elegy, from the midst of a mass of light in the sky, Prahevajra appeard, and a golden casket the size of a fingernail descended into Mañjuśrīmitra’s hand. That casket cantained the testament of Prahevajra, known as Three Words that Penetrate the Essence. It includes the following lines:
Homage to the realization of confidence in the self-awareness!
The [nature of] awareness is free from existence,
And various arisings of self-appearances are ceaseless.
So all the phenomenal existents are arising as the pure land of Dharmakaya,
And all the arisings are liberated in the nature [of awareness] itself.[View:] Introduction to the nature [one’s own awareness] itself.
[Path:] Becoming certain of the single point [of maintaining the nature itself].
[Result:] Having confidence in the liberation [of all into the primoridial nature].
Just by reading the testament, Mañjuśrīmitra attained a realization equal to that of Prahevajra.
