Dimension-by-Dimension Evidence

What each persona's writings reveal about their stance on each of the six dimensions.

Time

Udayana

Both — Ishvara is eternal and timeless; the created world undergoes cyclic creation and dissolution (srishti-pralaya). Time within each cycle is substantival and real (kala is one of the Vaisheshika categories). Discrete because the Nyaya-Vaisheshika ontology analyses time into atomic moments (kshana). Non-deterministic: human agents possess free will (svatantrya) under karmic constraints.

Space

Udayana

Space (dik/akasha) is one of the nine substances in Vaisheshika ontology — infinite, substantival, and the substratum of spatial relations. Three-dimensional and local: objects occupy determinate positions. The cosmos is spatially unbounded but atoms are finite.

Matter

Udayana

Atoms (paramanu) are eternal, indivisible, and combine under the will of Ishvara to form the composite objects of the world. Matter is conserved through cosmic cycles — atoms persist through dissolution and recombination. The Vaisheshika categories provide a realist ontology of substances, qualities, motions, universals, particulars, and inherence.

Observer

Udayana

The self (atman) is a permanent, immaterial substance that is the locus of knowledge, desire, and volition. Embodied in the current life, it persists across deaths. Knowledge is gained through valid means (pramanas): perception, inference, comparison, and testimony. Ishvara is the supreme observer with total knowledge; human observers have mediate, inferential access to truth.

Energy

Udayana

Not theorised as a separate concept. Causal efficacy belongs to substances and is ultimately grounded in Ishvara's will. The Vaisheshika category of karma (motion) covers the active force in physical change.

Information

Udayana

Knowledge (jnana) is a quality of the self. Once gained through valid pramanas, it is retained by the self. Ishvara's knowledge is total and eternal. The self's accumulated knowledge and karma are conserved across lives. Discrete because the Nyaya epistemology analyses cognition into distinct episodes (jnana-utpatti).

Internal Tensions

Where each persona's working synthesis strains against itself.

Udayana

Udayana's proofs for Ishvara presuppose the Nyaya-Vaisheshika category framework (atoms, inherence, universals) that his Buddhist opponents reject wholesale. The arguments are therefore circular from the Buddhist standpoint: the categories that require a divine arranger are themselves the contested premises. Within the Hindu tradition, the Advaita Vedantins (Shankara's school) found Udayana's personal theism too anthropomorphic and his atomism incompatible with the non-dual Brahman. The Navya-Nyaya school that followed Udayana largely set aside the theological ambitions in favour of pure logical formalism.
