Asanga
One of the most famous Indian saints, he lived in the fourth century. He received teachings from Maitreya and transcribed them as the ‘Five Treatises of Maitreya’. Together with Asanga's own commentaries, these texts became the basis for the philosophical schools known as Yogachara, or Chittamatra. See the story of Asanga in The Tibetan Book of Living and Dying, pages 125-126.
