|Chapter 1: Observing the Armies on the Battlefield of Kurukshetra|
vepathus ca sarire me
roma-harshas ca jayate
gandivam sramsate hastat
tvak caiva paridahyate
My whole body is trembling, my hair is standing on end, my bow Gandiva is slipping from my hand, and my skin is burning.
These symptoms are being displayed by Arjuna may resemble one is spiritual ecstasy (trembling, hair-standing), but they are factually coming out of the material anguish being felt by Arjuna. As a devotee he is naturally compassionate and soft-hearted, but since he is too much preoccupied with the material conception of life it can be inferred that he is displaying these symptoms because of excessive material attachments.
