Fantastic way to learn about Buddhism
The text makes the classical summary of the branches of Tibetan Buddhism available in a very pleasant and accessible manner. The contents represent a series of books written by a leading nonsectarian practitioner. Each specific book is available for a fraction of the print cost. Only reason that I did not give this 5 stars is that the publisher is slow to update it to new versions of iOS. I have refrained from updating my iPad to iOS 12 so as not to risk looking this app, as I did with earlier releases.
