Query: A demanding Masterpiece

The Cental Philosophy of Tibet by Robert A. F. Thurman (Princeton) is by far the most innovative and key texts to Tsong-kha-pa's teachings and life experience as it purports to reveal Tsong-kha-pa's own account of his experience of Enlightenment and his answer to many of the intellectual muddles, hyperintllectualisms, antirationalisms that befuddled and continues to perplex many contemporary monks and Buddhist practitioners. It is a demanding read but well worth the effort.
