As an animal open his mouth to eat another animal similarly Your mouths are open as if You may eat or swallow entire world within a moment.

O Lord Vishnu! You have variety of vivid colors, You are touching sky, Your mouths are wide, Your eyes are gigantic and shining. I am losing confidence and peace watching Your such Form. (Bhagwat-Gita: 11/24)

Arjuna has explained highs and wide of Divine God in 11/20 here only explaining only height of stunning aggressive Divine-God.

You are manifested Lord Vishnu who exist everywhere and to remove the burden of earth You have taken incarnation.

You have vivid colors which are very dazzling.

Your figure is such large that it touching sky. Which denote that as far Arjuna was able to see he was witnessing all around the figure of Divine-God, actually the figure was dramatically beyond that. The gifted divine vision to Arjuna was also not enough to see infinite unlimited Divine-God.

As an animal open his mouth to eat another animal similarly Your mouths are open as if You may eat or swallow entire world within a moment.

Your eyes are looking incredible and huge.

Arjuna was restless worried and surprise witnessing this manifested form of extremely aggressive Divine-God. Arjuna was not getting confidence from anywhere he was not able to attend peace.

Arjuna was astonished watching the Divine-God but Sanjay remain calm because it is said that Sanjay, Bidhur, Kunti and Vishma were not only older and experienced but already knowing the extraordinary Lord Krishna. Arjuna was not aware of the elements of Divine-God.
