Advaita Vedānta (Ādi Śaṅkarācārya): This verse underscores the non-dual reading of the Bhagavad Gītā, emphasizing the protection of the Supreme Good, which Shankara interprets as the realization of Brahman. In his commentary on the Bhagavad Gītā, Shankara explains that the phrase 'śreyaḥ sanumān upālayanti' implies the preservation of the higher knowledge that leads to the understanding of the identity of the individual self (ātman) with the ultimate reality (Brahman). This realization is what awakens one to 'That,' the Supreme Truth, beyond all duality. Shankara's interpretation of 'sarva-vatāṃ yat prabodhāt' suggests that this awakening is universal and encompasses all existence, leading to the understanding that the distinctions between the individual self and the ultimate reality are illusory, thereby pointing to the brahman-ātman identity. By focusing on the protection of this supreme knowledge, one transcends the mundane and achieves liberation.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): The Vaiṣṇava tradition interprets this verse with a strong emphasis on the devotional relationship between the jīva (individual soul) and Īśvara (the personal deity, often considered as Vishnu). Rāmānujācārya, in his commentary, suggests that 'śreyaḥ sanumān upālayanti' refers to the protection and cultivation of the highest good, which is the loving devotion to Īśvara. This devotion awakens the jīva to the true nature of reality, where the distinction between the individual self and Īśvara is not one of identity but of inseparable dependence. Rāmānujācārya interprets 'sarva-vatāṃ yat prabodhāt' as indicating that this awakening to the loving service of Īśvara is the source of all virtues and the ultimate goal of human existence. Madhvācārya, while also emphasizing devotion, would likely stress the importance of recognizing the distinction between the jīva and Īśvara, with 'That' referring to the supreme Lord Vishnu, whose grace alone can awaken the jīva to its true devotion-filled existence.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): This verse, when viewed through the lens of Neo-Vedānta, offers a profound message of universal applicability and practicality. Swami Vivekānanda, in his lectures and writings, often emphasized the importance of realizing the Supreme Good as a unifying principle that transcends sectarian divisions. He would interpret 'śreyaḥ sanumān upālayanti' as the cultivation of a higher, universal consciousness that encompasses all beings, leading to a life of service and harmony. Vivekānanda's teachings suggest that 'sarva-vatāṃ yat prabodhāt' points to the awakening of this universal consciousness within each individual, which is the source of all ethical and moral virtues. Similarly, S. Radhakrishnan, in his philosophical works, underscored the importance of this verse in promoting a universal religion, where the realization of the Supreme Good leads to a life of compassion, tolerance, and understanding, applicable to all aspects of contemporary life, thus bridging the gap between ancient wisdom and modern needs.
