Sadakata Chen, "Indian Sexual Culture Theory" - Sexuality as taught in Buddhist scriptures. A Reference Book that Truly Inquires into the Relationship between Buddhism and Sexuality.
This book is a straightforward discussion of the relationship between Buddhism and sex, something we are not usually exposed to.
I am now trying to show the back roads of Buddhism. Some Buddhist scholars may not like this. But what can we understand about Buddhism if we avoid the issue of sexuality, which is very important for human beings? In India, sexual love (karma) is one of the three major goals of life. I believe that the significance of Buddhism can be properly understood only when all aspects of human beings are known."
I believe that these words in this book are a very important recommendation.
