Wealth as Divine Resource
Thiraviyam (Tamil form of Sanskrit dravya = substance, material wealth, money) in Śrī Vaiṣṇava usage reframes money and material resources: they are not personal possessions but resources entrusted to the devotee by Bhagavān for use in His service.
The Doctrine of Non-Ownership
The tradition teaches śeṣatva at every level: not only the self (ātmā) and the body (deham) belong to Bhagavān, but all possessions (thiraviyam) as well. A Śrī Vaiṣṇava who internalizes this treats their wealth as the Lord's property temporarily placed in their stewardship. This naturally leads to generous use of resources for temple service, support of Ācāryas, tatiyārādhanam, and community welfare.
Historical Examples
The great Ācāryas of the tradition were known for their non-attachment to thiraviyam. Periyāzhvār offered the gold received from the king entirely to Bhagavān. Kūrattāzhvān did not accumulate wealth. These examples are not requirements but aspirational models of the tradition's teaching that thiraviyam, rightly understood, flows back to its Source.
