Regarding bodies
Although there are bodies, it is not impossible for the characteristics of the Vaikriya and similar bodies to exceed those of the Audahrika and others significantly.
The nature of the last two bodies, in terms of their temporal limits and ownership, possesses certain distinct characteristics compared to the first three bodies, which are elaborated upon in three subsequent points.
The nature of the Taijasa and Karmana bodies is such that they do not encounter resistance anywhere in the universe; even a hard object like a diamond cannot prevent them from entering, as they are extremely subtle. Although a solid object can resist another solid object, this law of resistance applies only to gross objects and not to subtle ones. A subtle object can enter everywhere without hindrance, like fire in iron.
Question: Shouldn't the Vaikriya and Ahāraka bodies also be considered non-resistant because they are subtle?
Answer: Indeed, they also enter without resistance. However, here, non-resistance means uninterrupted movement up to the ultimate limit of the universe. The Vaikriya and Ahāraka bodies have uninterrupted movement, but not throughout the entire universe; instead, they only dwell in specific parts of the universe, namely the Trasaṇāḍī.
Temporal limits: The Taijasa and Karmana bodies have an eternal relationship with the soul in terms of flow, unlike the first three bodies, which do not remain after a certain period. Therefore, the Audahrika and similar bodies are said to have a temporary relationship, whereas Taijasa and Karmana bodies have an eternal relationship.
Question: If they are eternally related to the soul, then their absence should never occur, because the 'eternal state' cannot be destroyed?
Answer: The two bodies are eternal not in relation to the individual but in relation to the flow. Hence, they can undergo decay and generation. Only those substantial entities that are eternal from an individual perspective do not perish, like atoms.
Ownership: All worldly beings possess the Taijasa and Karmana bodies, whereas the Audahrika, Vaikriya, and Ahāraka bodies are not held by all worldly beings. Thus, the owners of Taijasa and Karmana are all worldly beings, whereas the owners of the Audahrika and others are only a few beings.
Question: There must be some difference between Taijasa and Karmana, right? 1. Compare: "From the nonexistent, being cannot arise, but from being, that which exists can." - Gita, 2.16.
