Jamg n Kongtrul (1813-1899) was a versatile and prolific scholar. He has been characterized as a "Tibetan Leonardo" because of his significant contributions to religion, education, medicine, and politics.
"Jamgon Kongtrul's commentary on the slogans is one of the best books I studied. I was relieved that Buddhism was so simple. You can just follow the book and do as it says, which is extraordinarily powerful and such a relief."--Ch gyam Trungpa
