The Heart Sutra is the wisdom essence of the Prajnaparamita Sutras by the Buddha Shakyamuni in the Vulture's Peak in Raighrya. His Holiness Dalai Lama, the Buddha of Compassion is a living holder of the Madhyamaka philosohy and representative of the Nalanda tradition. Combined, they produce one of the highest espiritual teaching and delightful reading experience available for all buddhist practitioners
The book begins with an amazing introduction full of information about the main topics of the teachings of Lord Buddha and the historical origins of the Prajnaparamita texts.
The central topic of this teaching is the ultimate reality of Emptiness inseparable of Appearences. H.H. explains Shunyata from the Madhyamaka Prasangika philosophycal stream perspective, typical of the Gelug school. In this philosophical view there's no reference to the role of the observer and his co-arising (non -dualism) with the sourranding phenomenical appearences, neither any reference to Tatahagatarbha. Therefore I found Madhyamaka Prasangika an incomplete understanding of the nature of reality. Nevertheless it's a fundamental first approach to the teaching in this Sutra.
