Think of Einstein’s law of relativity where your vision is affected by where you sit on some frame of reference. Say you are riding a moving train and the only way you know you are moving rapidly is looking out the window but someone standing on the ground just sees a rail car whiz by them at 100 km/hr.
We don’t own objective perspective because we sit on our own subjective plain which hampers objectivity. So when a transgender person first discovers themselves they are sitting on a plain that doesn't correlate with what their brain is telling them. There is a disconnect between the observable world around them and how they are feeling inside and that disconnect doesn’t get repaired until that gap is addressed somehow.
The only way out is to reframe the reality around them that tells them there is something wrong with them. It prevents their self realization because much of what they have been taught is false and artificial and is unfortunately rooted in the irrationality of humankind.
Reframing your coordinate system becomes not only important but essential in order to make sense of the reality you are experiencing.
