B.G 11.20
The space between heaven and earth is indeed pervaded by you alone, and all the directions. Having seen your wondrous and terrible form, the three worlds are agitated, O one great-being.
Gīta Bhāshya 11.20
It is the same Lord who is present within father and earth, who pervades the space between earth and heaven. Lord's form is not necessarily fear-giving always. Based on one's capacity, some are pleased at the sight of his form, other's fears on His proximity.
"He who resides within mother and father in one form is also the one who is all-pervading in others."
Stated thus in the Vāruṇa Vedic testimonial. Accordingly, it is that same person only who pervades the space between heaven and earth.
"Behold my forms, O Pārtha."
- stating thus many forms have been promised. The mother and father are the earth and heaven.
"Let the earth not be the mother in the wicked-minded", "May the heaven be our sweet father".
From such usages, we come to realize that form is not necessarily fear-giving always. Since it (such fear) is absent for Nārada, the Lord shows it thus to some.
"Some are pleased at the sight of his form; someone fears on proximity; for some there is complete satisfaction."
- stated thus in the Vedic testimonial of Vāruṇa branch.
But not all see Him. Even without seeing, some observers perceive and describe it as fearsome it. So are the teachings in Gautama portion of Vedic testimonial:
"Some rejoice having seen the god; others fear even without seeing, as if they had. They see Him only with eyes withdrawn, since their minds have gone to Him.
- stated thus.
