Does soul have shape? Does that shape change from body to body?

From: Keshav

Do soul have shape if they have fixed size , what shape is it ?

Gita says soul is like a body with cloth over it , upanishad’s say it have a fixed size .

If we take it as correct , then in human body , soul must be with two hand’s and two leg’s .

and in body of fish it must be without hand and leg’s , do it mean that soul is formless , or it changes shape as per given body ?
