Why: Arjuna says heaven and earth and all the space between are pervaded by Krishna alone, the three worlds tremble seeing this wondrous, terrible form, naming both wonder and genuine fear as simultaneous, appropriate responses to what he's witnessing.

In life: awe and fear aren't actually opposites, genuine encounters with something vastly larger than yourself often produce both at once, and that combination is a normal, honest response, not a contradiction to resolve.

Teaching: if you've ever felt both wonder and fear simultaneously in the face of something genuinely significant, trust that combination as an honest, appropriate response rather than assuming you need to resolve it into just one feeling or the other.
