Shri Singha

Manjushrimitra ('jam dpal bshes gnyen), pron. Jampal Shenyen. An Indian master in the Dzogchen lineage and the chief disciple of Garab Dorje. In his role as a master in the lineage of the Sadhana Section of Mahayoga, he received the transmission of Yamantaka in the form of the Secret Wrathful Manjushri Tantra and other texts. Manjushrimitra was born in the Magadha district of India and was soon an adept in the general sciences and the conventional topics of Buddhism. After having become the most eminent among five hundred panditas, he received many teachings and empowerments from Garab Dorje, Lalitavajra, and other masters and reached the unified level of enlightenment, indivisible from Manjushri. Yamantaka appeared to him in person, conferred empowerment and transmitted the tantras and oral instructions. Among his chief recipients of this teaching were Hungkara, Padmasambhava, and Hanatela.
There seem to have been several masters with this name, but Guru Tashi Tobgyal in his Ocean of Wondrous Sayings to Delight the Learned Ones views them as being magical emanations of the same master. See also Sadhana Section.
