satyaṃ jñānaṃ anantaṃ brahma

brahma (the ultimate reality) satyam (is true) jñānam (is knowledge) anantam (is infinite)

Advaita Vedānta (Ādi Śaṅkarācārya): In his commentary on the Chāndogyopaniṣad, Ādi Śaṅkarācārya interprets 'satyaṃ jñānaṃ anantaṃ brahma' as underscoring the ultimate reality of Brahman, which is beyond human comprehension. He argues that 'satyaṃ' signifies the immutable nature of Brahman, 'jñānaṃ' denotes its all-encompassing consciousness, and 'anantaṃ' indicates its boundless and infinite essence. According to Shankara, this verse points to the nondual identity of Brahman and Ātman, emphasizing that the individual self (jīva) is not separate from the ultimate reality. He cites this verse in support of his notion of 'tat tvam asi' (that thou art), where the individual's true nature is revealed to be none other than Brahman itself. This realization is the key to liberation, as it dissolves the illusion of separation between the individual and the ultimate reality.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): In the Vaiṣṇava tradition, 'satyaṃ jñānaṃ anantaṃ brahma' is seen as a description of the supreme Lord (Īśvara) who is the embodiment of truth, knowledge, and infinity. Rāmānujācārya, in his Śrī Bhāṣya, interprets this verse as highlighting the Lord's sarvajña (all-knowing) and sarvaśakti (all-powerful) nature. The relationship between the jīva and Īśvara is one of servitude and devotion, where the jīva strives to realize its inherent dependence on the Lord. Madhvācārya, in his commentary, further emphasizes the distinction between the Lord and the individual self, highlighting the former's infinite and eternal nature. This verse, in the Vaiṣṇava tradition, serves as a reminder of the Lord's greatness and the individual's duty to cultivate devotion and knowledge in order to attain liberation.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekānanda, in his lectures and writings, often referred to the Upaniṣadic concept of Brahman as the ultimate reality that underlies all existence. He interprets 'satyaṃ jñānaṃ anantaṃ brahma' as a call to realize the infinite potential that lies within each individual. According to Vivekānanda, this verse points to the universal and eternal principles of truth, knowledge, and freedom that are the birthright of every human being. S. Rādhākrishnan, in his work 'The Indian Philosophy,' explains that this verse represents the essence of Indian thought, which seeks to uncover the unity and interconnectedness of all existence. In contemporary life, this verse can be seen as a reminder of the importance of pursuing knowledge, cultivating a sense of truth and integrity, and striving for the infinite possibilities that lie within each individual.
