Paltrul Rinpoche gave teachings on the wisdom chapter of this text to Ju Mipham Rinpoche (1846-1912). Ju Mipham Rinpoche is one of the great luminaries of the Nyingma tradition and is considered to be an emanation of Manjushri. He practiced most of his life in retreat where he composed texts for future students during his tea breaks. In this way, he authored volumes on Buddhist philosophy, commentaries on the sutras and the tantras and works on medicine, astrology, and divination. Ju Mipham Rinpoche composed this particular text, The Ketaka Jewel, in 1878 when he was 32 years old.
