Who are we? What is our essence? These questions have been asked since time immemorial. The present book gives an answer that, although it looks new, is actually more than 2500 years old. Using quotes from a number of Buddhist sutras, Master Pingshi Xiao firmly proves that each of us has a true self which is called Tathagatagarbha. This book is intended to help Buddhist practitioners in understanding better Buddha's Dharma and free themselves from ignorance. It is translated in Bulgarian.
