Krishna says, "The Supreme Lord dwells in the hearts of all living beings, and by His 𝙢𝙖𝙮𝙖 (cosmic delusion) makes all beings revolve as if attached to a 𝙮𝙖𝙣𝙩𝙧𝙖 (machine)" (18.61). This is another way of saying that we are just a 𝙉𝙞𝙢𝙞𝙩𝙩𝙖 𝙈𝙖𝙖𝙩𝙧𝙖 -an instrument in the hands of the almighty. Krishna explained the same in a different way when He said that even if Arjun, out of 𝘼𝙝𝙖𝙣𝙠𝙖𝙖𝙧, thinks that he will not fight his nature will still compel him to fight (18.59); we will be driven to do karmas, even when we don't want to do, out of our 𝙨𝙬𝙖-𝙗𝙝𝙖𝙫 (material nature) (18.60).

'Existence' is the coherence of the manifested, like the perishable physical entities, and the un-manifested which is eternal but can't be perceived by our senses. Krishna earlier explained this through the example of a string of pearls. The pearls representing manifested and the invisible string representing the un-manifested. Both of them together form a beautiful necklace. Krishna called this invisible force as Lord and says that it is so powerful that all beings are made to follow its dictate as if attached to a revolving machine. 

Krishna gives a simple solution and says, "Seek refuge in Him alone with all your being. By His grace you shall obtain the peace and the eternal abode" (18.62). Essentially, there is no point in fighting this powerful existence and instead it is prescribed to seek refuge with all our being. 

Thus, it is about realising that we are merely a 𝙉𝙞𝙢𝙞𝙩𝙩𝙖 𝙈𝙖𝙩𝙧𝙖 in the mighty machine called the universe and consequently attain the ultimate freedom (𝙢𝙤𝙠𝙨𝙝𝙖) through surrender. Otherwise, we will be compelled to do things which are decided by this eternal existence as a part of creative evolution which is nothing but a life of struggle, pain and misery.
