Krishna says, "I am the all-devouring death and birth of future beings. Amongst feminine qualities I am fame, prosperity, speech, memory, intelligence, courage, and forgiveness (10.34). 𝘽𝙧𝙞𝙝𝙖𝙩𝙨𝙖𝙢𝙖 of hymns in the 𝙎𝙖𝙢𝙖𝙫𝙚𝙙𝙖; I am Gayatri of metres, of months I am 𝙈𝙖𝙧𝙜𝙖𝙨𝙞𝙧𝙖𝙝, of seasons the spring (10.35). I am the gambling of the fraudulent, the splendor of the splendid. I am the victory, I am the resolve of the resolute, and the virtue of the virtuous (10.36). I am dand (sceptre) of the rulers, art of those who seek victory, I am also the silence of secrets, I am knowledge of knowers" (10.38).
He further says, "Amongst the descendants of 𝙑𝙧𝙞𝙨𝙝𝙣𝙞, I am Krishna, and amongst the Pandavas I am Arjun. Know me to be Ved Vyas amongst the sages, and Shukracharya amongst the seers" (10.37). Interestingly, Krishna says I am Arjun. One way to look at it is that HE is the best among archers. Another way is that when we find 𝙋𝙖𝙧𝙖𝙢𝙖𝙩𝙢𝙖 at the end of our spiritual journey, we invariably find HIM within us. Firstly, there is no way that we can be separate from existence. Secondly, we can never know others better than we know ourselves. So, we find HIM in ourselves and hence, Arjun himself is Krishna.
Krishna describes many of his glimpses/glories (𝙫𝙞𝙗𝙝𝙪𝙩𝙞). Though these are helpful in our spiritual journey, they are meant for Arjun and in the context of his time. Krishna is like a mirror and he is just reflecting Arjun's thoughts. If Krishna had narrated the Gita today, the description regarding 𝙫𝙞𝙗𝙝𝙪𝙩𝙞 would be completely different. One should be aware of this fact instead of glorifying any of these 𝙫𝙞𝙗𝙝𝙪𝙩𝙞. It shouldn't be like a baby who is looking at his mother's finger' pointing towards the moon instead of looking at the moon itself.
