The Challenge Bhagavad Gita As It Is 10.15:

Text

O origin of everything that is, O Lord of everything, O Lord of the demigods, O Lord of the universe, O best of all personalities, You know Yourself by your internal potency and nobody can understand you.

Purport.

Therefore the Supreme Personality of Godhead can be known by persons who are in confidence with the Supreme Personality by discharging devotional service and the example is Arjuna and his followers. Persons of demoniac or atheistic mentality cannot know Krishna, and simply mental speculation to detract the readers from the Supreme Personality of Godhead is a serious type of sinful activity. One who does not know Krishna should not try to comment on the Bhagavad Gita. Bhagavad Gita is the statement of Krishna and is it the science of Krishna. It should be understood from Krishna as Arjuna understood it. It should not be received from atheistic persons. As stated in the Srimad Bhagavatam 1.2.11, the Supreme Truth is realized in three aspects: as impersonal Brahman, localized Paramatma and at last as the Supreme Personality of Godhead. So this last step in understanding the Absolute Truth is the Supreme Personality of Godhead. A common man and even a liberated man has to realize impersonal Brahman or localized Paramatmam. Such persons may endeavor to understand the Supreme Personality from the verses of the Bhagavad Gita, which is being spoken by this person, the best personality, Krishna. Sometimes the impersonalist accepts Krishna as Bhagavan and they accept His authority. Even the liberated person cannot understand Krishna. Krishna is Purushottam. Still one may not understand that he is the father of all living entities. Therefore He is addressed as Bhuta-bhavana. And if it becomes known that He is the father of all living entities and still one may not know that He is the Supreme Controller, therefore He is addressed as Bhutesha, the Supreme Controller of everybody. And even if it becomes known that Krishna is the Supreme Controller of all living entities, still one may not know that He is the only one cause of all demigods. Therefore He is addressed here as Devadeva, the worshipful God of all demigods. And even one may know that He is the worshipful God of all demigods, one may not know that He is the Supreme Proprietor of everything. Therefore He is addressed herein as Jagatpate. Therefore the truth about Krishna is established in this verse by the realization of Arjuna and we should follow the footprints of Arjuna to understand Krishna as He is.

Hayagriva’s Illusory Bhagavad Gita As It Is NOT 10.15:

VERSE

Indeed, You alone know Yourself by Your own potencies, O origin of all, Lord of all beings, God of gods, O Supreme Person, Lord of the universe!

PURPORT

The Supreme Lord Krsna can be known by persons who are in a relationship with Him through the discharge of devotional service, like Arjuna and his successors. Persons of demonic or atheistic mentality cannot know Krsna. Mental speculation that leads one away from the Supreme Lord is a serious sin, and one who does not know Krsna should not try to comment on Bhagavad-gita. Bhagavad-gita is the statement of Krsna, and since it is the science of Krsna, it should be understood from Krsna as Arjuna understood it. It should not be received from atheistic persons.
The Supreme Truth is realized in three aspects: as impersonal Brahman, localized Paramatma and at last as the Supreme Personality of Godhead. So at the last stage of understanding the Absolute Truth, one comes to the Supreme Personality of Godhead. A liberated man and even a common man may realize impersonal Brahman or localized Paramatma, yet they may not understand God’s personality from the verses of Bhagavad-gita, which are being spoken by this person, Krsna. Sometimes the impersonalists accept Krsna as Bhagavan, or they accept His authority. Yet many liberated persons cannot understand Krsna as Purusottama, the Supreme Person, the father of all living entities. Therefore Arjuna addresses Him as Purusottama. And if one comes to know Him as the father of all the living entities, still one may not know Him as the supreme controller; therefore He is addressed here as Bhutesa, the supreme controller of everyone. And even if one knows Krsna as the supreme controller of all living entities, still one may not know that He is the origin of all the demigods; therefore He is addressed herein as Devadeva, the worshipful God of all demigods. And even if one knows Him as the worshipful God of all demigods, one may not know that He is the supreme proprietor of everything; therefore He is addressed as Jagatpati. Thus the truth about Krsna is established in this verse by the realization of Arjuna, and we should follow in the footsteps of Arjuna to understand Krsna as He is.
