After trembling and bowing, Arjuna opens his mouth — and what comes out is not a cry of terror. It is a hymn. 'Sthane' — it is right, it is fitting. The world rejoices in Your glory. Devotion rises naturally toward You. Demons scatter in every direction. The Siddhas bow.
There is a remarkable composure in this shloka, especially given what Arjuna has just witnessed. He is not pretending the terror did not happen. He is placing it in context. Yes, the vision was overwhelming. But it is right that it was overwhelming. A glory this vast should inspire exactly this — joy in the good, fear in the wicked, reverence in the wise.
The contrast between the Rakshasas and the Siddhas is telling. The same divine presence that sends demons running in panic also draws perfected beings into joyful prostration. The cosmic form has not changed. Only the capacity of the beholder determines whether the response is terror or devotion.
