Final answer:
Reshmina cannot touch the blinded American soldier because she does not have the same physical beauty as the speaker, Arjuna.
Step-by-step explanation:
The reason Reshmina cannot touch the blinded American soldier is because she does not have beautiful eyes like the speaker, Arjuna, who describes his own eyes as dark as death. The line emphasizes the contrast between Reshmina's physical appearance and the speaker's perception of her.
While Reshmina may be skilled in archery and capable of hitting any target, she cannot touch the soldier's heart because she lacks the beauty that the speaker possesses.
