Yeshe Zhonnu, who was also known as Jñānakumara, was born into the Nyak clan in Po, Yarlung during the mid 8th century. His father was Takra Lhanang and his mother was Suza Gonkyi.
He was given the name Gyelwe Lodro due to an unusual mole on his neck that resembled a crossed vajra.
He received his ordination from Śāntarakṣita and was initiated by Padmasambhava into the Vajrāmṛṭa maṇḍala, one of the eight Heruka.
He practiced at Yarlung Sheldrak and obtained the ability to bring forth water from the ground. Padmasambhava also initiated him into the Kabgye and his flower fell on the central deity of the maṇḍala, Chemchok Heruka.
Nevertheless, Jñānakumara is mainly recognized for his Vajrakīla practice and transmission which he got from Vimalamitra. His transmission lineage is called the Nyak Luks Purba.
The 25 disciples of Padmasambhava also called as Guru Rinpoche were instrumental in the spread of Buddha's teachings throughout Tibet. They emerged as masters, having achieved great wisdom, understanding, and success.
These Mahasiddhas are believed to have special future incarnations due to their connection with Padmasambhava's terma treasures.
To this day, these disciples continue to be reborn as Tertons, imparting the teachings of Padmasambhava in a contemporary and authentic way to new .
