The Vedika tradition offers a multifaceted view of “this whole” is Agni [SB 7.3.1.12], pervaded antarikṣa, [Tāṇḍya Br, 15.12.2] and the sūkṣmāntarikṣa, the humans or more aptly, Jīva, along with Śarīraṁ [SB 6.1.1 4]. Rooted in the Ṛta, which represents the cosmic order or the universal principles that govern the world and the universe. Human existence is deeply interconnected with the cosmos, governed by Dharma. The idea of interconnectedness and unity of the sūkṣmāntarikṣa and antarikṣa, “This Whole” is agni [SB 7.3.1.12] = prajāpatiḥ [SB 6.2 1.23] = puruṣaḥ [SB 6.1.1.5] = brahma [SB 10.4.1.5]. It is beautifully encapsulated [ Chāndogya Up. 6.1.7], which says, "All this is, indeed, Brahman" and ascertains further by “Tat Tvam Asi” [ Chāndogya Up. 6.8.7], hence establishes cosmic responsibilities. [RV. 1.89.6] giving sūkṣmāntarikṣa the greatest strength in its capacity to depict the complexities and vulnerabilities of human existence. What we call Prakṛti, i.e., the nature is intricately connected to Ṛta, [RV.1.90.6; RV. 1.164.23; RV. 10.190.1], and [Taittiriya Saṁhitā, 1.2.8.1]. The order and balance between the antarikṣa and the sūkṣmāntarikṣain, the natural world as a reflection of the cosmic order. [RV.1.89.2; RV.1.25.8], harmony in nature, [RV. 5.44.4; RV. 7.49.4] and moral and ethical [RV. 10.191.1] are established. This paper, explores man and nature from the above perspective, which leads ultimately to the space and time to which the modern natural and mathematical sciences have started converging.
