By Me, being gracious, this supreme form has been shown to you, O Arjuna, through My own yoga: radiant, all-embracing, endless, primal, [a form] of Mine which by none other than you was seen before.

▸Bhagavadgītābhāṣyam
अर्जुनं भीतम् उपलभ्य, उपसंहृत्य विश्वरूपम् , प्रियवचनेन आश्वासयन् श्रीभगवान् उवाच —
मया प्रसन्नेन, प्रसादो नाम त्वयि अनुग्रहबुद्धिः, तद्वता प्रसन्नेन मया तव हे अर्जुन, इदं परं रूपं विश्वरूपं दर्शितम् आत्मयोगात् आत्मनः ऐश्वर्यस्य सामर्थ्यात् । तेजोमयं तेजःप्रायं विश्वं समस्तम् अनन्तम् अन्तरहितं आदौ भवम् आद्यं यत् रूपं मे मम त्वदन्येन त्वत्तः अन्येन केनचित् न दृष्टपूर्वम् ॥ ४७ ॥
In plain words
Seeing how frightened Arjuna had become, Kṛṣṇa let the universal form fold back in, and, speaking gently to comfort him, the Blessed Lord said —
It was I, in my own graciousness — grace simply means a heart turned toward you in favor — it was I, out of that very grace, who showed you this supreme form, this universal form, Arjuna, through nothing but my own power, the sheer capability of my own sovereign Self. Blazing with light, made of splendor, holding this entire universe within it, without end, without limit, existing since before time began — this form of mine has never been seen by anyone but you. No one else. Not ever.
Close to the Sanskrit
Having perceived Arjuna to be frightened, having withdrawn the universal form, comforting [him] with affectionate words, the Blessed Lord said —
By me, gracious — grace means an attitude of favor toward you — possessing that, being gracious, by me was this supreme form, the universal form, shown to you, O Arjuna, out of [my] own yogic power, out of the capability of the Self's own sovereignty. Full of splendor, abounding in radiance, universal, entire, endless, without limit, existing from the beginning, primeval — which form of mine has not been seen before by anyone other than you, apart from you, by anyone at all.
