Mirror mirror on e wall

We all know that what we see in the mirror is not real. That it is just a reflection and lacks real form. Hence we sort of discount that image in the mirror.

Of course we still scrutinize it when we are vain but it is a known fact that the image is "false", as in it doesnt have its own life.

If we can accept the fact that the image in the mirror is false, than why do we hold on to e delusion that our body/form is real? I thought it was a very good parallel.

Of course e fact that our form is empty is harder to accept. But if we can be taught that e mirror image is false, we too in time, can learn and realise that our physical form too is empty and false.
