na hi dehāt nirviṇṇasya pravṛttiḥ śāstrato bhavet | na ca dehāya deha-prāṇaḥ śarīre asminn asaṅgataḥ

na hi (not indeed) dehāt (from the body) nirviṇṇasya (of one who is detached) śāstrataḥ (according to śāstra) pravṛttiḥ (inclination) bhavet (should be) | na ca (not indeed) dehāya (for the body) deha-prāṇaḥ (the life of the body) asmin (in this) śarīre (body) asaṅgataḥ (not connected)

Advaita Vedānta (Ādi Śaṅkarācārya): This verse underscores the non-dual nature of reality, emphasizing that one who is detached from the body transcends the bounds of scriptural injunctions. Shankara's commentary on the Muṇḍakopaniṣad highlights the idea that the knower of Brahman, having realized the identity of the individual self (ātman) with the ultimate reality (Brahman), is no longer bound by the limitations of the physical body or the dictates of scripture. In his view, the life force (prāṇa) is not inherently connected to the body but is a manifestation of the universal energy that pervades all existence. Thus, this verse points to the brahman-ātman identity, where the individual self, freed from bodily attachments, realizes its true nature as one with the absolute, unconditioned 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, in his commentary, suggests that detachment from the body implies a recognition of the body as a mere instrument, not the true self. This understanding leads to a deeper devotion to Īśvara, who is the ultimate controller of all life forces, including the prāṇa. Madhvācārya, with his emphasis on the difference between the individual soul and the Supreme Lord, might view this verse as indicating the potential for the soul to achieve liberation through devotion, but always maintaining a distinction between the soul and God. Thus, the life force, though a gift from Īśvara, is a separate entity from the body and the individual soul, pointing to a complex interrelationship in the Vaiṣṇava cosmology.

Neo-Vedānta (Swami Vivekānanda / S. Rādhākrishnan): Swami Vivekānanda often emphasized the practical and universal application of Vedāntic principles. This verse, in the context of Neo-Vedānta, can be seen as a call to recognize the deeper, spiritual nature of the self, beyond the physical body. Vivekānanda, in his lectures and writings, frequently discussed the importance of realizing one's true nature as spirit, not limited by the confines of the body. Similarly, S. Radhakrishnan, in his philosophical works, highlighted the universal message of the Upaniṣads, including the idea that true freedom and knowledge come from transcending the ego and the body. This verse, therefore, serves as a reminder of the human potential for spiritual growth and self-realization, encouraging individuals to look beyond the mundane and seek the timeless and universal truths that connect all humanity.
