satyaṃ jñānaṃ anantaṃ brahma

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

Advaita Vedānta (Ādi Śaṅkarācārya): This verse from the Chāndogyopaniṣad is pivotal in Advaita Vedānta for establishing the non-dual nature of reality. Śaṅkarācārya, in his commentary on this Upaniṣad, interprets 'satyaṃ jñānaṃ anantaṃ brahma' as underscoring the ultimate truth that Brahman is the only reality, beyond human perceptions of time, space, and causality. The attributes of truth, knowledge, and infinity are not accidental qualities of Brahman but its inherent nature, pointing to its unchanging and all-encompassing essence. This understanding is crucial for realizing the identity of the individual self (ātman) with the universal self (Brahman), a cornerstone of non-dualistic philosophy. Shankara's reasoning emphasizes that the realization of Brahman as truth, knowledge, and infinity leads to the dissolution of ignorance, facilitating the understanding that the ultimate reality is not distinct from the self.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): In the Vaiṣṇava tradition, this verse is seen as an affirmation of the supreme nature of Īśvara (the personal God), often identified as Viṣṇu. Rāmānujācārya, in his commentary, leans towards a theistic interpretation, where Brahman's attributes of truth, knowledge, and infinity underscore its personal and benevolent nature. This perspective emphasizes the relationship between the individual soul (jīva) and God, highlighting the path of devotion (bhakti) as a means to realize the true nature of Brahman. Madhvācārya, from a Dvaita (dualistic) viewpoint, would interpret this verse as reinforcing the distinction between the individual self and the supreme self, while still acknowledging the supremacy of Brahman. Both Rāmānuja and Madhva would agree, however, that this verse is foundational in understanding the divine and its attributes, guiding the devotee towards a deeper devotional life.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekānanda and S. Rādhākrishnan, among other modern interpreters, see in this verse a powerful message of universal applicability. For Vivekānanda, the attributes of truth, knowledge, and infinity in Brahman signify the potential for human perfection and the unity of all existence. He often cited such Upaniṣadic passages to underscore the importance of realizing one's true self and the interconnectedness of all beings. Rādhākrishnan, with a philosophical bent, emphasizes the rational and ethical implications of this verse, suggesting that the pursuit of truth and knowledge, as attributes of the ultimate reality, should guide human conduct and society towards a more harmonious and enlightened state. Both thinkers stress the practical application of these ancient wisdoms in contemporary life, advocating for a synthesis of spiritual insight and social responsibility, and the cultivation of a universal outlook that transcends sectarian and national boundaries.
