As long as you think someone else is responsible for the way you are, you cannot become the way you want to be. - Sadhguru.
The personality is always outside dependant. Then what does it mean to be the way we want to be?
We can't be as a person anyhow we want as per our wish. Because everything outside molds it every moment in so many ways.
That simply implies we can be in such way that is completely untouched by anything outside at all. Which also means we are not our persona. We are beyond it.
As long as we be as persons we can't remain untouched by other's doing. We all are connected in one way or the other. So, what one does definitely sets an impact over others.
But, if we remain in a state within where not even our personality reaches then we could be just how we want to be. Without any disturbances.
