Different belief systems describe ๐๐๐ง๐๐ข๐๐ฉ๐ข๐ in different ways. Depending on our belief system, the appearance of ๐๐๐ง๐๐ข๐๐ฉ๐ข๐ changes and if HE appears in front of us in a different shape or form, it would be impossible to recognise.
Similarly, Arjun was treating Krishna like a friend for decades. He couldn't recognise that Krishna is ๐๐๐ง๐๐ข๐๐ฉ๐ข๐ till he saw HIS ๐๐๐จ๐๐ฌ๐๐ง๐ค๐ค๐ฅ๐๐ข. He profoundly apologises and says that "Thinking of You as my friend, I presumptuously addressed You as, 'O Krishna', 'O Yadav', 'O my dear Friend'. I was ignorant of Your majesty, showing negligence and undue affection. And if, jestfully, I treated You with disrespect or insulted you, while playing, resting, sitting, eating, when alone, or before others —for all that I crave forgiveness" (11.41-11.42).
Like Arjun, the same would happen to any of us. When we reach that eternal state of surrender, we realise that everyone around us is a part of the same ๐๐๐ง๐๐ข๐๐ฉ๐ข๐ . Every person, animal or tree would become ๐๐๐ง๐๐ข๐๐ฉ๐ข๐ , whether they are aware of it or not. Our earlier behaviour with them would look awful and the only option is to seek forgiveness like Arjun is doing. Many cultures preach and practice forgiveness, gratitude and prostration to attain this eternal state of freedom.
In the eleventh chapter of Srimad Bhagavatam, there is a long conversation between Krishna and his childhood friend ๐๐๐๐๐ซ. At the end of the conversation, ๐๐๐๐๐ซ requests a very simple path toward salvation. Krishna replies that prostrate to a thief, a donkey or an enemy like you prostrate to ME. This path is very simple to understand but very tough to inculcate. This is the same as when Krishna said 'to realise all beings in the self; self in all beings and see HIM everywhere' (6.29) which can be easily achieved by dropping hatred (5.3).
