"Dedicated to the longevity of Knowledge on this planet" - Tarthang Tulku Rinpoche
Surativajra, having received these teachings directly from Vajrasattva, bestowed them upon Manjushrimitra, the most learned individual of the time, and advised him to write commentaries. While practicing in the caves near Bodh Gaya, Manjushrimitra gave important Atiyoga teachings so Sri Simha, Jnanasutra and Vimalamitra. As the head of five hundred Panditas at Nalanda, Vimalamitra was most likely the one to transmit this Manjushri lineage within the great university, where the study and practice of Namasamgiti became the basis for understanding the higher teachings. Sri Simha presumably transmitted the text to the Lotus-Born Guru Padmasambhava, whose own handwritten devanagari copy for recitation was found at Samye monastery. According to Manjushrimitra, this text of Namasamgiti is part of the hundred thousand chapters of the Manjushri Sutra, and is interpreted in distinctive ways in accord with different traditions.
