Arjuna inspite of having the knowldege of shaastra got so delusioned, all stories we here in Puranas of learned sages...returning to samsara

the knowledge of shastras are like rules and guidelines to live in society. what Arjuna asked or needs is intimate , for himself. as per Dharma as a kshatriya his duty is to fight, Dharmaraj knew it so he did not hesitate to fight. what Arjuna thought was- Is war and killing worth it? I think this is the question which elevates him above all and a worthy disciple of Lord Krishna. Gita answers this intimate question- Is my suffering Real? This is the beauty of it
