Advaita Vedānta (Ādi Śaṅkarācārya): In his commentary on the Bhagavad Gītā, Śaṅkarācārya interprets this verse as underscoring the non-dual nature of reality. He emphasizes that the concept of 'faith' or 'sattva' is ultimately a product of the individual's cognitive framework, which is bound by the limitations of the ego. According to Śaṅkarācārya, the verse suggests that the Supreme Being rewards the devotees in accordance with their faith, but this is merely an illusion perpetuated by the ego. In reality, the individual self (ātman) is identical with the ultimate reality (brahman), and the distinction between the two is a mere intellectual construct. This interpretation is in line with Śaṅkarācārya's broader philosophical stance, as outlined in his commentary on the Brahma Sūtras, where he argues that the ultimate reality is beyond human comprehension and can only be intuited through self-inquiry and contemplation.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): Rāmānujācārya, a prominent Vaiṣṇava theologian, interprets this verse as highlighting the reciprocal relationship between the individual self (jīva) and the Supreme Lord (Īśvara). According to Rāmānujācārya, the verse suggests that the Lord responds to the devotee's faith and devotion by granting them the desired rewards. This interpretation emphasizes the personal and relational aspect of the divine, where the Lord is seen as a loving and responsive deity who interacts with the devotee in a manner that is tailored to their specific needs and aspirations. In contrast, Madhvācārya, another influential Vaiṣṇava thinker, offers a more nuanced interpretation, arguing that the verse underscores the Lord's sovereignty and freedom in responding to the devotee's prayers. Madhvācārya's commentary highlights the complex and multifaceted nature of the divine-human relationship, where the Lord's responses are guided by his own inscrutable will and purpose.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekānanda, a key figure in the modern Vedānta movement, interprets this verse as emphasizing the importance of faith and self-effort in the pursuit of spiritual growth. According to Vivekānanda, the verse suggests that the individual's faith and devotion are the primary determinants of their spiritual progress, and that the Supreme Being responds to the devotee's efforts by granting them the necessary guidance and support. This interpretation highlights the practical and universal application of the verse, where the emphasis is on the individual's agency and responsibility in shaping their own spiritual destiny. In his lecture 'The Ideal of a Universal Religion,' Vivekānanda elaborates on this theme, arguing that the ultimate goal of spiritual practice is to realize the unity and interconnectedness of all existence, and that this can be achieved through a combination of self-inquiry, devotion, and service to others. Similarly, S. Rādhākrishnan, a prominent philosopher and statesman, interprets the verse as underscoring the importance of cultivating a sense of reverence and awe in the face of the unknown, and of recognizing the intricate web of relationships that binds the individual to the world around them.
