What does this mean the impure can neither stand nor sit with purity?

The phrase "the impure can neither stand nor sit with purity" suggests that those who harbor impurity—whether moral, spiritual, or ethical—cannot coexist comfortably or authentically with those who embody purity. It implies a fundamental incompatibility between purity and impurity, indicating that the presence of impurity disrupts the integrity and sanctity associated with purity. Essentially, it highlights the idea that purity requires a certain state of being that cannot be tainted or compromised by impurity.
