When Does Impurity Transfer
So if i touch food with impure hands its impure even if no traces? And utensils will be pure unless traces are present?
Once you have noticed real impurity falls into the food or water, it makes it impure. Now, if you touch it, your hands are impure, no matter whether it shows traces or not. But when you have not seen or noticed a thing get impure, now it can only be decided that the thing shows the traces of impurity. If you can stretch your imagination, nothing can be pure. In short, consider something impure only when you see it contaminated; if you haven’t seen it contaminated, then it is only the traces of impurity that can tell something is impure. When you do not find a trace, consider it pure. You are not responsible for untoniced impurity.
