na hi deho dehāt bṛthā prajāyate

deho (body) dehāt (from another body) bṛthā (in vain) na hi (not indeed) prajāyate (is produced)

Advaita Vedānta (Ādi Śaṅkarācārya): The verse 'na hi deho dehād bṛthā prajāyate' from the Muṇḍakopaniṣad underscores the non-dual nature of reality, pointing to the ultimate identity of Brahman and Ātman. Śaṅkarācārya, in his commentary on the Brahma Sutras, emphasizes that the phenomenal world, including the human body, is a manifestation of Brahman. The body, thus, is not born in vain but serves as a vehicle for the realization of the true Self, which is none other than Brahman. This verse supports the Advaita view that the distinction between the individual self (jīva) and the supreme Self (Brahman) is illusory, and the ultimate goal is to realize this unity. Śaṅkarācārya's reasoning on related passages, such as the Taittiriya Upanishad, further reinforces the idea that the body's existence is meaningful only insofar as it facilitates the pursuit of Self-knowledge, leading to the understanding that the body is not an end in itself but a means to transcend its limitations and realize the non-dual truth.

Vaiṣṇava tradition (Rāmānujācārya / Madhvācārya): The Vaiṣṇava interpretation of 'na hi deho dehād bṛthā prajāyate' highlights the purposeful creation of the body by Īśvara for the jīva. Rāmānujācārya, in his commentary on the Brahma Sutras, emphasizes the real and eternal distinction between the soul and God, yet underscores their reciprocal relationship. The body, born from another body, serves as an instrument for the jīva to attain its ultimate goal of loving devotion to Īśvara. Madhvācārya, with his emphasis on the difference between the individual selves and the Supreme, would interpret this verse as underscoring the dependency of the jīva on Īśvara for its very existence and purpose. The verse thus encourages devotion and recognition of one's place within the cosmic order, emphasizing that the body's existence is a gift from Īśvara to facilitate the jīva's spiritual journey towards moksha, or liberation, through bhakti, or loving service.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekānanda, interpreting the verse 'na hi deho dehād bṛthā prajāyate' in the context of modern Vedānta, sees it as a call to recognize the body as a temple of the divine, a vessel for the realization of one's higher nature. He emphasizes in his lectures and writings that the purpose of human life is not merely physical existence but the pursuit of spiritual growth and self-realization. Vivekānanda connects this verse to the broader theme of the potential divinity of man, suggesting that the body is a tool, not an end, in the journey towards discovering one's true, divine nature. Similarly, S. Radhakrishnan, in his philosophical expositions, highlights the universal and practical application of this verse, seeing it as a reminder of the intrinsic value and sacredness of human life, encouraging individuals to live a life of purpose, morality, and spiritual aspiration, thereby transcending the limitations of the physical body and realizing one's true essence.
