SrI: SrImathE SatakOpAya nama: SrImathE rAmAnujAya nama: SrImath varavaramunayE nama:
yaṁ hi na vyathayanty ete
so ’mṛtatvāya kalpate
Be it mild or acute, no arrow-hits can torment a person of courage, – one who is able to look upon an inevitable pain as equal to pleasure. That is the person to whom the discharge of duties, incumbent on his status (caste, occupation, etc.) in society, – such as engaging in war (for a Kshatriya)- without anticipating any benefits therefrom – paves the way to immortality. Such a person wins immortality, Arjuna! not thou who canst not suffer pain. That conduct (or character) i.e. bearing (up, or patient suffering without complaint) is a necessary sign of the eternality of ātmās (souls).
Whether it be the eternality of ātmās, or the decaying character of the bodies that is regarded, it has been shown by verse: viz:
‘The wise, grieve not either as respects bodies, or as respects ātmās, etc.’, (Bh: Gi: ii-11)
that no cause, in any case, exists for regret.
This subject will now be expanded:
