TRANSLATION
Whenever and wherever there are peaceful, equipoised devotees who are well behaved and decorated with all good qualities, that place and the dynasties there, even if condemned, are purified.
PURPORT
Wherever exalted devotees stay, not only they and their dynasties but the entire country is purified.
