Spiritualism

Both Arjuna and Karna were master marksmen with a bow 

and arrow. Whereas Arjuna was the favorite student of 

Dronacharya, Karna had lord Parasurama as his teacher. 

Thus he, Bhishma and Dronacharya were almost brothers.

Arjuna is the Soul and lord Krshna is the Super Soul in all of 

us .
