I'm not surprised that the site has lots of mis-translated words. I have just used an online translater to do the job as best as it is able. It's not meant to be a great translation, but just something more readable than the English site, to those who don't speak English. I'm hoping that, for the most part, the pictures and videos will speak for themselves.
I don't have the resources to seriously undertake a properly translated site. But thanks so much for the offer!

"There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open."
