satyaṃ jñānaṃ anantaṃ brahma

brahma (Brahman) satyaṃ (is true) jñānaṃ (knowledge) anantaṃ (infinite)

Advaita Vedānta (Ādi Śaṅkarācārya): The verse 'satyaṃ jñānaṃ anantaṃ brahma' underscores the non-dual nature of reality, emphasizing that Brahman is the ultimate truth, infinite, and the essence of knowledge. Shankara, in his commentary on the Taittirīya Upaniṣad, highlights the importance of understanding Brahman as the absolute reality that transcends all limitations. He argues that the knowledge of Brahman is not a mere intellectual comprehension but a direct, immediate experience that reveals the identity of the individual self (ātman) with the universal self (Brahman). This verse, therefore, points to the ultimate reality where the distinctions between the individual self and the universal self dissolve, affirming the brahman-ātman identity. Shankara's reasoning on closely related passages, such as the statement 'tat tvam asi' (That thou art), further reinforces the non-dual interpretation of this verse, guiding the seeker towards the realization of the absolute, unqualified Brahman.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): The Vaiṣṇava tradition interprets the verse 'satyaṃ jñānaṃ anantaṃ brahma' through the lens of devotion and the relationship between the individual soul (jīva) and the Supreme Lord (Īśvara). Ramanuja, in his commentary on the Brahma Sutras, understands Brahman as the supreme personality of Godhead, whose essential nature is characterized by truth, knowledge, and infiniteness. This interpretation emphasizes the dependent relationship of the jīva on Īśvara, where the jīva's existence and knowledge are derived from and sustained by Īśvara. Madhva, on the other hand, stresses the distinction between the Supreme Lord and the individual souls, highlighting the Lord's sovereignty and the souls' complete dependence on Him. Both Ramanuja and Madhva agree, however, on the verse's affirmation of Brahman's infinite and all-knowing nature, which forms the basis of devotional practices and the pursuit of liberation through the grace of Īśvara.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekananda, in his lectures and writings, often referenced the Upaniṣads to highlight the universal principles that can guide contemporary life. The verse 'satyaṃ jñānaṃ anantaṃ brahma' is seen as a call to recognize and realize the infinite potential that lies within every individual. Vivekananda emphasized the importance of self-realization, not merely as an intellectual exercise but as a practical means to unlock one's true nature, which is characterized by truth, knowledge, and infiniteness, mirroring the attributes of Brahman. S. Radhakrishnan, in his philosophical works, further developed this idea by discussing the importance of integrating spiritual values into daily life, citing this verse as a foundation for understanding the human condition and our place in the universe. Both thinkers saw this verse as a reminder of the universal and eternal principles that underlie human existence, encouraging individuals to strive for a life of truth, knowledge, and service, thereby actualizing the infinite potential that resides within.
