That voice is your conscience, your morals, your individuality. No one can take that from you unless you let them. They can take everything from you in material terms – your house, your job, your ability to speak and move freely. They cannot take away who you truly are. They can never truly know you, and that is your power.
But to protect and wield this power, you need to know yourself – right now, before their methods permeate, before you accept the obscene and unthinkable as normal.
