Puruṣa — The Cosmic Person, Lord of the Universe
Puruṣa (Sanskrit: पुरुष, traditionally analyzed as puri śete — 'one who lies in the city [of the body]', or as derived from pūr meaning 'complete/full', conveying the supremely complete Being) is one of the most theologically rich and multi-layered terms in Indian philosophy. Its meanings span at least three major contexts: (1) in Sānkhya philosophy, Puruṣa is pure, passive, contentless consciousness — one of the two ultimate principles alongside Prakṛti; (2) in the Ṛgveda's Puruṣa Sūkta (hymn 10.90), Puruṣa is the cosmic Person whose primordial sacrifice generates the entire universe — from whose body the cosmos, the four varṇas, and all beings emerge; and (3) in Vedānta and specifically in Viśiṣṭādvaita, Puruṣa in its highest sense (Puruṣottama) is Bhagavān Nārāyaṇa — the supreme Person who pervades and transcends both the kṣara-puruṣa (the perishable) and the akṣara-puruṣa (the imperishable), as declared in the Bhagavad Gītā chapter 15.
The Puruṣa Sūkta is foundational to Śrī Vaiṣṇava theology and liturgy. Its vision of Bhagavān as the cosmic Person whose thousand heads, thousand eyes, and thousand feet encompass the entire universe — yet who is ten fingers beyond it — captures in vivid imagery the Viśiṣṭādvaita understanding of Bhagavān as both the sarvāntaryāmin (inner controller of all) and the transcendent who exceeds the cosmos He inhabits. The Sūkta's statement pādo'sya viśvā bhūtāni tripādasyāmṛtaṃ divi ('One quarter of Him is all beings, three quarters is immortal in heaven') is interpreted by Rāmānuja to mean that Bhagavān's nature as bound and embodied universe is only a partial expression of His infinite, transcendent nature. The Mahāpuruṣa Vidyā and Puruṣa Sūkta recitation remain central to Śrī Vaiṣṇava ritual even today.
The Bhagavad Gītā's fifteenth chapter, Puruṣottama Yoga, is the locus classicus for Viśiṣṭādvaita's understanding of Bhagavān as the supreme Puruṣa. Kṛṣṇa declares: dvāv imau puruṣau loke kṣaraś cākṣara eva ca / kṣaraḥ sarvāṇi bhūtāni kūṭastho'kṣara ucyate ('There are two puruṣas in this world: the perishable and the imperishable; the perishable is all beings, the imperishable is the unchanging') — and then: uttamaḥ puruṣas tv anyaḥ paramātmety udāhṛtaḥ / yo lokatrayam āviśya bibharty avyaya īśvaraḥ ('But the highest Puruṣa is yet another — the Paramātman, who entering the three worlds sustains them, the imperishable Īśvara'). The Puruṣottama is thus not merely the sum of kṣara and akṣara but is qualitatively beyond them — the personal God who sustains, pervades, and transcends the universe while remaining the beloved Lord whose grace is the sole means of liberation. In Śrī Vaiṣṇava theology, recognizing Bhagavān as Puruṣottama is itself a form of liberating vidyā.
