To make dirt you grind up rocks and add decaying organic matter and microbes, some insects and worms and their eggs. A little splenda if you have a sweet tooth.

Maybe the guy has a "revised" version of Deuteronomy, because in the "traditional" edition it is very meat/fish friendly:-)
Deuteronomy 12:20:
"When the LORD your God has enlarged your territory as he promised you, and you crave meat and say, "I would like some meat," then you may eat as much of it as you want. " (For details check Deu 20)

Similar way I failed to find any references to shower, jogging in the Good Old Book, but found plenty of references to washing/bathing, working (farm work is very strenous exercise). So I do not know how the "renouncing showering, jogging" Bible based.

About the dirt. I agree, this is a simple advertisement for the guy's dirt product... (Oh well, faith can move mountains....)
