I went on a `survival trip` once, and I was freezing, very tired and hungry all the time. From that experience I came to the conclusion that it`s not good for me. I suffered, and don`t want to do that again.
I would love to interact directly with nature like they do on Thiaoouba, but I can`t. I don`t have the knowledge yet.
I see that as a basic understanding. Take care of the tool (physical body), and use it to help develop the mind. For me, the best way to take care of the tool is to have a comfortable life.
