Īśvara-gītā: The Supreme Lord as Brahman, the Source of Creation, and the Inner Self
ब्रह्मा योगी परमात्मा महीयान् व्योमव्यापी वेदवेद्यः पुराणः / एको रुद्रो मृत्युरव्यक्तमेकं बीजं विश्वं देव एकः स एव
brahmā yogī paramātmā mahīyān vyomavyāpī vedavedyaḥ purāṇaḥ / eko rudro mṛtyuravyaktamekaṃ bījaṃ viśvaṃ deva ekaḥ sa eva
He is Brahmā, the supreme Yogi, the Paramātman—vast and all-pervading like space—knowable through the Vedas, the Ancient One. He alone is Rudra; he is Death; he is the one Unmanifest; he is the seed and the universe. That one God alone—he indeed is all this.
Lord Kurma (Vishnu) teaching as Ishvara (Ishvara Gita discourse)
Primary Rasa: adbhuta
Secondary Rasa: raudra
It identifies the Paramātman as the single all-pervading Reality—both transcendent (the one Unmanifest) and immanent (as seed and as the universe), knowable through the Vedas yet beyond limited forms.
The verse points to īśvara-centric yoga: contemplation of the one Supreme as the inner Self and as the cosmic ground (bīja/avyakta), a core Ishvara Gita approach that supports one-pointed meditation and non-dual insight.
By declaring the One God as Rudra while spoken by Lord Kūrma, it presents a Shaiva–Vaishnava synthesis: Shiva (Rudra) and Vishnu (Ishvara speaking) are affirmed as one Supreme Reality.
