Vanaratna
At Śrī Dhānya-kaṭaka mahā-caitya he met, in a vision, with Māhasiddha Shavaripa and received from him his unique transmission of the Sadaṅga-yoga, the Six-limbed Yoga of the Kālacakra tradition. Vanaratna eventually beheld a vision of Avalokiteśvara, who advised him to go to Tibet.
Vanaratna visited Tibet in 1426, 1433 and 1453 and spread the Kālacakra lineage and instructions of Paṇḍita Vibhūti-candra there, especially the Sadaṅga-yoga according to Anupamarakṣita, and many other teachings. He also assisted in the translation of many texts and treatises. Such famous Tibetan masters as Gö Lotsawa Shönnu Pal (1392-1481) and Thrimkang Lotsawa Sönam Gyatso (1424-1482) were his close students. He also spent time in Bhutan, where even nowadays there is a temple, near Paro, with a sacred statue of his and a rock that bears his name in old Bengali script. Vanaratna spent his final years in the Gopicandra Vihara in Patan/Kathmandu, now known as Pinthu Bahal, and passed away there. (Source: RY wiki)
