The vishuddhi chakra, located in the pit of your throat, literally means “filter.” If your vishuddhi becomes powerful, you have the ability to filter everything that enters you. Or in other words, once your vishuddhi is very active, you grow so powerful that external nature has no influence over you. Indian iconography depicts Adiyogi, or Shiva, with a blue throat, because he is capable of filtering all the poisons of the outside world and preventing them from entering his system by stalling them in his throat.
