Advaita Vedānta (Ādi Śaṅkarācārya): The verse 'satyaM jñānaM anantaM brahma' underscores the non-dual nature of reality as per Advaita Vedānta. Shankara's commentary on the Taittirīyopaniṣad, particularly on this verse, highlights that Brahman, the ultimate reality, is characterized by its truthfulness (satyam), knowledge (jñānam), and infiniteness (anantaM). This characterization points to the identity of Brahman with the individual self (ātman), suggesting that the ultimate goal is to realize this non-dual identity. Shankara's reasoning emphasizes that the qualities of Brahman are not separate attributes but are Brahman itself, leading to the understanding that Brahman is not just a static truth but the dynamic, all-encompassing reality. This verse, in the context of Shankara's philosophy, serves as a foundational statement for the pursuit of self-knowledge and the attainment of liberation through the realization of the brahman-ātman identity.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): In the Vaiṣṇava tradition, particularly through the lens of Rāmānujācārya, the verse 'satyaM jñānaM anantaM brahma' is seen as an affirmation of the personal nature of the ultimate reality, Īśvara. Rāmānuja interprets the qualities of Brahman—truth, knowledge, and infiniteness—as indicating a personal God who is both the object of devotion and the source of all knowledge. The relationship between the individual self (jīva) and Īśvara is one of dependence, with the jīva seeking liberation through devotion and self-surrender to Īśvara. Madhvācārya, on the other hand, emphasizes the distinction between the individual selves and Īśvara, yet also underscores the devotional path to realizing one's true nature and achieving union with God. For both, this verse highlights the importance of recognizing and worshiping a personal deity as the path to spiritual liberation, emphasizing the role of devotion and knowledge in achieving salvation.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekānanda and S. Rādhākrishnan, key figures in Neo-Vedānta, interpret the verse 'satyaM jñānaM anantaM brahma' as a call to recognize the universal and eternal principles that underlie all existence. Vivekānanda sees this verse as emphasizing the importance of realizing one's true nature, which is divine and infinite. He connects this realization with the practical application of service to humanity, suggesting that understanding our inherent divinity inspires compassion and action in the world. Rādhākrishnan, focusing on the philosophical aspects, interprets 'anantaM brahma' as the infinite that is the basis of all existence, highlighting the unity and interconnectedness of all things. Both thinkers connect this verse to contemporary life by emphasizing the pursuit of knowledge and truth not merely as intellectual exercises but as paths to self-realization and service to society, thereby underscoring the relevance of ancient wisdom to modern challenges and aspirations.
