SB 1.14.40
kaccin nabhihato ’bhavaih
sabdadibhir amangalaih
na dattam uktam arthibhya
asaya yat pratisrutam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Has someone addressed you with unfriendly words or threatened you? Could you not give charity to one who asked, or could you not keep your promise to someone?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
A ksatriya or a rich man is sometimes visited by persons who are in need of money. When they are asked for a donation, it is the duty of the possessor of wealth to give in charity in consideration of the person, place and time. If a ksatriya or a rich man fails to comply with this obligation, he must be very sorry for this discrepancy. Similarly, one should not fail to keep his promise to give in charity. These discrepancies are sometimes causes of despondency, and thus failing, a person becomes subjected to criticism, which might also be the cause of Arjuna’s plight.
