yasyā dharme hatā śūro, tasya nāhatasya kutaḥ śṛte

Advaita Vedānta (Ādi Śaṅkarācārya): This verse underscores the non-dual nature of reality, pointing to the brahman-ātman identity. Shankara's commentary on the Brahma Sutras, particularly in the context of the Mahābhārata, emphasizes that true bravery lies not in physical prowess but in the recognition of one's true nature as unchanging and indestructible. The killing in righteousness (dharme yasyā hatā śūro) symbolizes the destruction of ignorance, not the physical body. Shankara's reasoning in his commentary on the Bhagavad Gita (especially in chapters 2 and 11, where duty and the nature of the self are discussed) further clarifies that the bravery mentioned here refers to the courage to seek knowledge of the Self. This understanding liberates one from the cycle of birth and death, illustrating the ultimate non-duality of the universe and the individual's place within it as an expression of Brahman. Thus, the verse serves as a metaphor for the spiritual journey, where the 'killing' is a transcendence of earthly attachments and ego, leading to the realization of the ultimate reality, Brahman.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): The Vaiṣṇava tradition interprets this verse through the lens of devotion and the relationship between the jīva (individual soul) and Īśvara (the Supreme Lord). Rāmānujācārya's Visishtadvaita Vedanta views the bravery in righteousness as a means to attain unity with God, emphasizing the path of loving devotion (bhakti) as the primary means to achieve spiritual liberation. The 'killing' of a brave man in righteousness is seen as a sacrifice of one's ego and desires for the sake of serving the Lord, leading to a deeper intimacy with the Divine. Madhvācārya's Dvaita Vedanta, while differing in its interpretation of the nature of the relationship between the individual and God, also sees this verse as highlighting the importance of righteous action (dharma) as a means to please the Lord and attain liberation. Both Ramanuja and Madhva, through their commentaries on key Upanishads and the Bhagavad Gita, emphasize the role of divine grace and devotion in achieving the ultimate goal of union with Vishnu, underscoring the personal and relational aspects of spiritual pursuit.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekananda and S. Radhakrishnan, key figures in the Neo-Vedanta movement, interpret this verse as a call to universal action and service. They emphasize the practical application of spiritual principles in everyday life, making the pursuit of righteousness and bravery relevant to contemporary challenges. Vivekananda, in his lectures and writings, notably 'The Complete Works of Swami Vivekananda', often discussed the need for selfless service and the cultivation of inner strength and courage, seeing these as essential for individual and societal transformation. Radhakrishnan, in his philosophical works, such as 'The Hindu View of Life', highlights the importance of living a life of righteousness and the pursuit of knowledge as a path to realizing the universal and eternal principles that underlie all existence. Both thinkers connect the verse's theme of 'killing in righteousness' to the idea of overcoming one's lower nature and selfish desires, advocating for a life of service, compassion, and self-discipline as the means to achieve both personal growth and the betterment of society.
