BG Chapters 7 - 12

BG 7.19, Purport:

This verse is very nicely explained in the Third Chapter (verses 14 and 15) of the Śvetāśvatara Upaniṣad:

sahasra-śīrṣā puruṣaḥ

sahasrākṣaḥ sahasra-pāt

sa bhūmiṁ viśvato vṛtvā-

tyātiṣṭhad daśāṅgulam

puruṣa evedaṁ sarvaṁ

yad bhūtaṁ yac ca bhavyam

utāmṛtatvasyeśāno

yad annenātirohati

"Lord Viṣṇu has thousands of heads, thousands of eyes and thousands of feet. Entirely encompassing the whole universe, He still extends beyond it by ten fingers' breadth. He is in fact this entire universe. He is all that was and all that will be. He is the Lord of immortality and of all that is nourished by food." In the Chāndogya Upaniṣad (5.1.15) it is said, na vai vāco na cakṣūṁṣi na śrotrāṇi na manāṁsīty ācakṣate prāṇa iti evācakṣate prāṇo hy evaitāni sarvāṇi bhavanti: "In the body of a living being neither the power to speak, nor the power to see, nor the power to hear, nor the power to think is the prime factor; it is the life air which is the center of all activities." Similarly Lord Vāsudeva, or the Personality of Godhead, Lord Śrī Kṛṣṇa, is the prime entity in everything. And because Vāsudeva is all-pervading and everything is Vāsudeva, the devotee surrenders in full knowledge (cf. Bhagavad-gītā 7.17 and (BG 11.40).

BG 11.40, Translation and Purport:

Obeisances to You from the front, from behind and from all sides! O unbounded power, You are the master of limitless might! You are all-pervading, and thus You are everything!

Out of loving ecstasy for Kṛṣṇa, his friend, Arjuna is offering his respects from all sides. He is accepting that He is the master of all potencies and all prowess and far superior to all the great warriors assembled on the battlefield. It is said in the Viṣṇu Purāṇa (1.9.69):

yo 'yaṁ tavāgato deva

samīpaṁ devatā-gaṇaḥ

sa tvam eva jagat-sraṣṭā

yataḥ sarva-gato bhavān

"Whoever comes before You, even if he be a demigod, is created by You, O Supreme Personality of Godhead."
