A worth reading classical Tibetan Buddhist book by Patrul Rinpoche introduces readers into the depth of Tibetan Buddhism. It is one of the rare classical books translated into English language by the Padmakara Translation Group trying to reach out to the wider audiences.
The technical aspects of the different stages of meditations are briefly described, which I believe that would be beneficial if practiced consistently. Some of the higher meditation techniques are also briefly described which obviously seem to be unnatural, but practical. Well, it’s all about the enlightenment and to achieve it, the book has it the right path.
The fact impermanence of earth or life and the universe itself has been revealed; which also includes the beings which live in the outer universes. Obviously the principle of cause and effect are comprehensively described and the solutions revealed too.
As everyone is well aware about the Karmic effect, brief confrontations with the bad Karma and accumulation of good Karma is very well instructed.
A certain part of Guru Yoga and the ultimate method for arousing the wisdom of realization are well instructed attributing how capable we are and how much perseverance and patience we have.
So as the title of the book, the teachings in the book are based on the teachings by his Master/teacher of the author without much manipulation.
