yes yes Inside!
No external circumstance can determine your freedom. ALTHOUGH it looks real that what happens in this physical world takes responsibility in the amount of freedom it is an illusion.
Indeed we have to learn to look inside and realise that we are free. We born free we are free sometimes we feel we are slaves such contradiction is due to a lack of self knowledge and the illusion that keep us trap.
If you release yourself from within believe me (I am experiencing it) the outer world will match in accordance the end resut will be: I am experiencing the freedom in the physical world once manifested and felt by my self.
