The Eight Manifestations of Padmasambhava do not depict different
Padmasambhavas, but reflect his ability to appear according to
different needs and demands. In fact, they are called in Tibetan Guru
Tsen Gyé, the eight ‘names’ of the Guru; each manifestation
demonstrates a different principle that unveils the innermost nature

The Dakini Yeshe Tsogyal had a vision in which she saw a manifestation of Guru Rinpoche called Immense Vajra Ocean in the direction to the east.
Each of the pores in his body held one billion realms and in
each realm there were one billion w...orld systems. In each of these
world systems there were one billion Guru Rinpoches who each created one billion emanations. Each of these emanations carried out the activity of taming one billion disciples. She then saw the same display in each of the other directions and in the center.
In this world of Jambudvipa, Guru Rinpoche is known as just one nirmanakaya who tames beings but according to the different capacities and giftedness of people he is perceived in various ways.The history of the Oral Transmission of Kilaya and most Indian sources explain that he was born as the son of a king or a minister in Uddiyana; while the terma treasures for the most part narrate that he was miraculously born. In some texts he is said to have appeared from a bolt of lightning at the summit of Mount Malaya. Each of these wondrous stories differ in many ways. This is indeed a topic that lies far beyond the reach of an ordinary person's intellect.
