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 establishing the non-dual nature of reality. Śaṅkarācārya, in his commentary on the Upaniṣads, interprets 'satyaṃ jñānaṃ anantaṃ brahma' as affirming the ultimate reality, Brahman, as the essence of truth (satya), knowledge (jñāna), and infinity (ananta). He reasoning on the Mahāvākya 'Tat tvam asi' (That thou art) implies that the individual self (ātman) is not different from Brahman, underscoring the brahman-ātman identity. This verse, therefore, supports the Advaitic view that the distinctions between the individual self and the ultimate reality are illusory, and true knowledge (jñāna) of Brahman leads to the realization of this non-dual essence. Śaṅkarācārya's commentary on this verse emphasizes the attainment of liberation through the understanding of Brahman as the all-encompassing and timeless truth, ultimately leading to the dissolution of the distinctions between the individual and the divine.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): In the Vaiṣṇava interpretation, this verse highlights the attributes of the supreme being, Īśvara, as truth, knowledge, and infinity. Rāmānujācārya, in his Bhrama Sutras, interprets Brahman as the personal God with infinite qualities, emphasizing the path of devotion (bhakti) as the means to realize this truth. For Rāmānujācārya, the relationship between jīva (the individual soul) and Īśvara is one of dependence, where the jīva seeks liberation through devotion and surrender to the infinite and all-knowing Īśvara. This verse, therefore, is seen as an affirmation of the devotional approach to realizing God, where the knowledge of God's infinite and true nature is a precursor to a deeper, personal relationship with the divine. Madhvācārya, while agreeing on the personal nature of God, would further emphasize the distinction between the jīva and Īśvara, advocating for a devotional path that acknowledges and worships this distinction.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekānanda and S. Radhakrishnan, key figures of Neo-Vedānta, bring a modern and universal interpretation to this ancient verse. According to Vivekānanda, the attributes of Brahman as truth, knowledge, and infinity are not just metaphysical concepts but also have practical implications for human life. In his lectures, he often emphasized the importance of realizing one's true nature as a means to achieve inner peace and outer harmony. This verse, for Vivekānanda, is a call to action, urging individuals to seek the truth within themselves and to strive for infinite knowledge and understanding. Radhakrishnan, building on this idea, interprets the verse in the context of contemporary life, suggesting that the pursuit of truth, knowledge, and the infinite is a universal quest that transcends religious and cultural boundaries. He advocates for a synthesized approach, combining the philosophical insights of the Upaniṣads with the challenges of modern life, thereby making the wisdom of this verse accessible and relevant to the global community.
