Why can't The Dwarf leave the flask?


The Dwarf in the Flask, of _Fullmetal Alchemist: Brotherhood_ , is seen
trapped within a flask during his first appearance.

At one point in the series, The Dwarf states that his greatest wish is to
leave the flask (from [FMA Wikia](http://fma.wikia.com/wiki/Father#Pre-
Amestris)):

However, due to the emboldened part above, it appears the flask is somehow
keeping him alive (though he is only corked inside it). How does it do this,
and how would he die if he left?




Because he had no form on his own. He's basically an essence of God, created
from Hoenheim's blood.

If his flask would somehow break, his being would dissipate into the space,
and lose his form and living consciousness.

Think of it as a soul with no body. Stuffed inside of a container, if that
container would break, the soul wouldn't have anywhere to reside, and leave
the world. (Al is a slightly different case, his soul is _bound_ to the seal
on the back of his neck).
