In English
If we look at it from the point of view of science, from every little part of our body several small particles are going into our body. These particles and radiations which are going in by the millions are invisible and you do not see them. It is not as if they emanate from outside and go inside. Even from our body, they are being continuously sent out. These emanations go inside as well as outside. This is the reason why there is a possibility of your getting a disease if you go to a bad place. If a place is unclean and dirty, we should immediately cleanse the place and cleanse ourselves.
