Advaita
कुतश्चागम्यते त्वेतात्र्रितयेऽपि निबोध मे । पुमान्सवर्गतो व्यापीत्याकाशवदयं यतः ॥ ५६ ॥
kutaścāgamyate tvetātrritaye'pi nibodha me | pumānsavargato vyāpītyākāśavadayaṃ yataḥ || 56 ||
แท้จริงแล้วหลักนี้เกิดมาจากที่ใด? โปรดอธิบายให้เรารู้ชัด แม้โดยจำแนกเป็นสามประการ. เพราะปุรุษะนี้พร้อมด้วยหมวดหมู่ทั้งปวง แผ่ซ่านทั่วทุกแห่งดุจอากาศ

It frames a core moksha inquiry: if the Self is all-pervading like space, its ‘origin’ cannot be understood as a physical birth; the verse pushes the seeker toward a higher, metaphysical explanation of Puruṣa as ever-present and not limited by location.
By portraying the supreme Person as all-pervading, it supports bhakti as universally accessible—devotion is not confined to a place or ritual setting, because the Lord/Self is present everywhere, like space.
The verse primarily belongs to moksha-dharma (Vedantic inquiry) rather than a technical Vedanga; its practical takeaway is disciplined questioning (vicāra) and clear categorization (‘threefold explanation’) as a method for correct understanding.
