Arjuna says: "The Gandiva is slipping from my hand. My skin is burning. I cannot even stand. My mind is spinning." The Gandiva — Arjuna's legendary bow, a weapon so heavy that no one else in the three worlds could lift it — is falling from his grip. When the warrior loses hold of his weapon, it is not just his fingers that have failed. His will has broken.
A warrior's weapon is an extension of his spirit. When the spirit cracks, the weapon follows. The Gandiva slipping is not about physical weakness. Arjuna has the strength of a demigod. What he lacks at this moment is the will to use that strength against the faces he has just recognized.
"Bhramativa cha me manah" — my mind is reeling, as if spinning in circles. This is the most serious symptom of all. The body had already failed — limbs weak, mouth dry, skin aflame. Now the mind itself has given way. Arjuna is completely overwhelmed. The greatest archer the world has known stands in his chariot, unable to hold his bow, unable to stand, unable to think.
