The eleventh chapter of the Bhagavad Gita is Vishwaroopa Darshana Yoga. In this chapter, Arjuna requests Krishna to reveal His Universal Cosmic Form that encompasses all the universes, the entire existence. Arjuna is granted divine vision to be able to see the entirety of creation in the body of the Supreme Lord Krishna.
The Blessed Lord said: I am the world-destroying Time, [Time: The supreme God with His limiting adjunct of the power of action.] grown in stature [Pravrddhah, mighty] and now engaged in annihilating the creatures. Even without you, all the warriors who are arrayed in the confronting armies will cease to exist!OPEN VERSE
Therefore you rise up, (and) gain fame; and defeating the enemies, enjoy a prosperous kingdom. These have been killed verily by Me even earlier; be you merely an instrument, O Savyasacin (Arjuna).OPEN VERSE
You destroy Drona and Bhisma, and Jayadratha and Karna as also the other heroic warriors who have been killed by Me. Do not be afraid. Fight! You shall conquer the enemies in battle.OPEN VERSE
Sanjaya said: Hearing this utterance of Kesava, Kiriti (Arjuna), with joined palms and trembling, prostrating himself, said again to Krsna with a faltering voice, bowing down overcome by fits of fear:OPEN VERSE
Arjuna said: It is proper, O Hrsikesa, that the world becomes delighted and attracted by Your praise; that the Raksasas, stricken with fear, run in all directions; and that all the groups of the Siddhas bow down (to You).OPEN VERSE
And why should they not bow down to You, O exalted [i.e. not narrow-minded.] One, who are greater (than all) and who are the first Creator even of Brahma! O infinite One, supreme God, Abode of the Universe, You are the Immutable, being and non-being, (and) that which is Transcendental.OPEN VERSE
