In this verse, Arjuna moves beyond the simple act of witnessing to the visceral experience of ontological shock. He realizes that the spatial dimensions—heaven, earth, and the interstitial space—are not containers for God, but are themselves held within the boundless expanse of the Divine. The term 'ekena' (by You alone) emphasizes the Advaitic truth that multiplicity is merely a projection; the underlying reality is a singular, undivided consciousness that is simultaneously immanent and transcendent. By perceiving the 'ugram' (terrible/formidable) aspect of this cosmic totality, Arjuna recognizes that time, dissolution, and creation are synchronized within the Divine. The trembling of the three worlds signifies the psychological dissolution of the ego when it finally confronts the scale of the Infinite, which defies all binary frameworks of existence and non-existence. From the perspective of Bhakti, this revelation serves to strip away Arjuna's lingering familiarity with Krishna as merely a friend and relative. The awe-struck 'Mahātman' (Great Soul) address acknowledges Krishna as the Universal Purusha. This shift in perception is essential for the seeker; it marks the transition from seeing God as an object of limited affection to experiencing God as the total Ground of Being. The fear present in the 'three worlds' is the natural reaction of the individual soul (jiva) realizing that its small, separate identity is being subsumed into the massive, kaleidoscopic truth of the Divine Will, which operates beyond human concepts of morality or comfort.

True spiritual vision begins when the ego recognizes that its fragmented perception is merely a ripple within the singular, infinite, and awe-inspiring reality of the Divine.
