Sanskrit
इहैकस्थं जगत्कृत्स्नं पश्याद्य सचराचरम् । मम देहे गुडाकेश यच्चान्यद्द्रष्टुमिच्छसि ॥
ihaikasthaṃ jagat kṛtsnaṃ paśyādya sacarācaram mama dehe guḍākeśa yac cānyad draṣṭum icchasi
Translation
Here, to-day, behold the whole universe, movable and immovable, standing in one in My body, O Gudâkesha, with aught else thou desirest to see.
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
“Ihaikasthaṃ” — here, standing-in-one — is the claim being staged: the entire universe, moving and unmoving, gathered into a single body, on this particular day, on this particular battlefield. The blank-cheque close (“with aught else thou desirest to see”) is an open invitation Arjuna hasn’t asked for yet and, going by verses 45-46, will come to regret taking Krishna up on. The epithet Guḍākeśa — “conqueror of sleep/drowsiness” — is pointed here: whatever is about to happen, Arjuna is being addressed as someone with no excuse to look away.
