arthaḥ

येषामर्थे काङ्क्षितं नो राज्यं भोगाः सुखानि च

arthe — sake

Those for whose sake we would want a kingdom, and pleasures, and happiness — they are the ones standing here, ready to give up their lives and their wealth:

यावानर्थ उदपाने सर्वतः संप्लुतोदके

arthaḥ — purpose

Whatever use a small pool of water has, a great lake has too. So it is with all the scriptures for one who has understood.

नैव तस्य कृतेनार्थो नाकृतेनेह कश्चन

arthaḥ — gain

Such a person gains nothing by acting and loses nothing by not acting, and depends on no creature for anything.
