Gyaza Kongjo, or Wencheng Gongzhu, was a Tang Dynasty noblewoman who was married to the Tibetan king Songtsen Gampo around the year 641. She is credited with bringing the Jowo Śākyamuni statue housed in the Lhasa Jokhang, and with inspiring the king to build a series of temples across the Tibetan Plateau in order to subjugate the realm and establish Buddhism there. She is considered by some to be an incarnation of White Tārā.
Gorub Lotsāwa Chokyi Sherab was a translator active in the eleventh century, during the Later Transmission of Buddhism to Tibet. Trained in central Tibet, he traveled to Kashmir, Nepal, and India and studied with multiple Buddhist teachers there, as well as with Rongzom Chokyi Zangpo later in his career. Dozens of translations in the Kangyur and Tengyur are credited to him.
