(* Avalokitesvara Bodhisattva is also known as: Contemplator of the World's Sounds/Guan Shi Yin/Guan Zi Zai Bodhisattva)
Translated during the Tang Dynasty by Shramana Bhagavat-dharma from west India.
Thus I have heard, once Sakyamuni Buddha was at Potalaka Mountain, in
the treasure-adorned Way-place in Avalokitesvara's palace, sitting on a
precious Lion-Throne adorned in purity with countless multifarious
Mani-jewels. Hundreds of precious streamers and banners were hanging all
around.
At that time, the Tathagata, who was sitting on his throne, intending to
explain a teaching of the Total-Retention Dharani, was along with
innumerable Bodhisattva-Mahasattvas, whose names are: Dharani King
Bodhisattva, Treasure King Bodhisattva, Bhaisajya-Raja(Medicine King)
Bodhisattva, Bhaisajya-Samudgata(Medicine Superior) Bodhisattva,
Avalokitesvara Bodhisattva, Maha-stamaprapta(Great Strength)
Bodhisattva, Avatamsaka Bodhisattva, Great Sublime Bodhisattva, Precious
Deposits Bodhisattva, Virtue Store Bodhisattva, Vajragarbha
Bodhisattva, Akasagarbha(Space Store) Bodhisattva, Maitreya Bodhisattva,
Samantabhadra(Universal Goodness) Bodhisattva, Manjusri Bodhisattva,
and so on. Such Bodhisattva-Mahasattvas are all great Dharma-Princes who
had been empowered through their crowns (Abhiseka).
