This handbook, Buddhism 101—Questions and Answers, is a selected collection of Buddhist basic teachings for beginners. While composing this book, we thought in particular about those Buddhists who just initiatively started to study and practice Buddhism in environments of multiple religions and multiple cultures. Therefore, the basic themes introduced here serve to provide readers with a general view of the Buddha’s teachings in regard to both theory and practice. Given the limitations of a handbook, we dare not go further into intensive issues of Buddhist philosophy as doing so may lead to difficulties for beginners. However, the selected questions discussed here are the core teachings of Buddhism. As a beginner, you need to master these teachings firmly and precisely before going further into the Buddhist studies. We hope that this handbook will be a useful ladder to help you along the way in your learning and practicing.
