The question asks about the philosophical principle where the shape of the 'Jiva' is determined by the shape of the body it inhabits.
In Jain philosophy, the 'Jiva' (soul) is fundamentally formless. However, it takes on the characteristics, including the form and dimensions, of the physical body it is associated with during its existence in the cycle of rebirth.
This specific concept, linking the perceived shape of the 'Jiva' to the physical confines of its current body, is a core tenet of Jaina thought.
Other schools like Advaita, Samkhya, or Bauddha have different views on the nature of the soul and its relationship with the body, which do not align with this principle.
