Inside cleanliness, daily clearing the bowels. In the yoga system this is very necessary. They have got a system if the bowel is not clear, then dhokhi—it is called dhokhi. The intestines should be cleared. So they have a process. Some of the yogīs, they are so expert that they can take out the intestine from the abdomen and clear it and put it again. Yes.

So inside cleanliness is very important thing. If the bowel is not clear, if the stools are congested . . . the appendicitis disease, it means that those who are constipated, gradually inside their stool becomes dry, and it becomes a block to the intestine. So if it becomes too much blocked, if it is not possible to be cleared, then the modern medical science, they cut the abdomen and cut the part and clear it, and again stitch it. That is appendicitis, so far I know—I am not medical man. There are so many diseases that is due to this non clearance of the intestines.
