June Gītā: 11.40

namaḥ purastād atha pṛiṣhṭhatas te
namo ’stu te sarvata eva sarva
ananta-vīryāmita-vikramas tvaṁ
sarvaṁ samāpnoṣhi tato ’si sarvaḥ

O Lord of infinite power, my salutations to You from the front and the rear, indeed from all sides! You possess infinite valor and might and pervade everything, and thus, You are everything.

Bhagavad Gītā 11.40

Chapter 11 is where Krishna grants Arjuna divine vision. This allows Arjuna to see Krishna in his full nature as God himself.

Everything in the Gita so far has worked up to this point.   Arjuna now understands his purpose in life, his dharma, to fight in the battle. He realises that Krishna is not just his friend and charioteer but divinity itself. In this Sloka, Arjuna use the word “Namah” meaning I bow to you indicating his reverence for Krishna and the change in their relationship.

This is the chapter where Arjuna reaches samadhi. Initially he see Krishna as God personified and then in this Sloka he realises  Krishna as infinite and all pervading.   

In his translation of the Gita, Eknath Easwaren describes these two states as two different forms of samadhi, corresponding with the different stages of samadhi described in the Yoga Sutras. Initially, Arjuna is in savikalpa samadhi.  He sees Krishna as a personal manifestation of God wearing a crown and holding a discus. In this Sloka Arjuna’s samadhi deepens and he reaches nirvikalpa (formless) samadhi. Completely absorbed all forms disappear and Arjuna is aware of the infinite all pervading presence that is consciousness itself.
