Translation:

Now, I am in contact with cows by spirit, not by eyes. My senses stopped, but my spirit was moving. According to the natural physiological structure of cattle, cut into the gap between the bones and muscles of cattle and eat along the gap between joints. According to the original structure of the cow, where the tendons and veins are connected and where the bones and muscles are combined, no knife has ever been used, let alone the big bones!
