The world that unfolds within the book is a world where you can freely fly across the sky riding on clouds.
In this world, it seems foolish for four people to go through hardship and suffering to obtain treasure (Buddhist scriptures) instead of taking the convenient route and enjoying a comfortable and pleasant journey.
In this way, everyone should think about what true happiness is at least once in their life.
How can we speak of happiness without experiencing pain and hardship? This book will help you think about what true happiness is and how to attain it.
