This book contains a minute fraction of the infinite knowledge of the Buddha. It describes in detail the Buddha's marvelous realization about the law of Dependent Origination (paṭiccasamuppāda). After realizing the truth about Dependent Origination, the Buddha taught us that the endless suffering in the cycle of birth and death is a result of the principle of cause and effect. The path to Enlightenment according to the Dhamma is entirely dependent on one's own effort. Read this book carefully and remember well the vital points of Dhamma it contains. Strive hard to acquire wisdom and develop wise consideration. Realization of the Dhamma does not happen without effort!
