|Hugelkultur in a Nutshell|
I will suggest some evidence in support of this point of view. One of the schools of permaculture is called "Natural Farming". It was founded by a Japanese fellow by the name of Masanobu Fukuoka and is based on a combination of both a spiritual revelation and also a lifetime of practical research. So, if you will, it is a combination of both "merging with the Dao" and also "kungfu". He was very explicit about using traditional Daoist/Zen language to describe his personal experiences of developing his permaculture system. In support of this argument, I would suggest that people look at this YouTube video. It is somewhat long, but I think that most readers would find it worth it. Pay special attention to the language that he uses to describe his personal journey. I would argue that it could have easily been lifted from an ancient Daoist text.
