Je Tsongkapa’s Illumination of the True Thought is one of the greatest presentations of emptiness in history. This work in turn is an explanation of Entering the Middle Way, by Master Chandrakirti, who lived during the seventh century and was commenting himself upon the 3rd‐century author Arya Nagarjuna, whose Root Text on the Wisdom of the Middle Way is considered the greatest commentary of all time upon the emptiness teachings of the Buddha himself.
Geshe Michael has said that in his opinion these are the greatest books about emptiness that have ever been written, and to have an opportunity to go through these books in an authentic way is extremely rare. Just to be able to hear them is unbelievably rare. It took him eight years in the monastery to learn these texts, after 2 years everyone else in the class dropped out and Geshe Michael was the only student left.
Thus does the happiness we have found
Rest, perfectly, within the mind
Of a child of the Victors;
Thus does its light, like a moonstone,
Lend great beauty to this ultimate setting;
Thus does it clear away and conquer
All the masses of darkness.
