Many kṣatriyas have laid down their lives on the battlefield for their nations, but hardly a person can be found who has given up all his property and his accumulated wealth in charity to a person worthy of the gift. As stated in Bhagavad-gītā (17.20) :

dātavyam iti yad dānaṁ dīyate ’nupakāriṇe deśe kāle ca pātre ca tad dānaṁ sāttvikaṁ smṛtam

“That gift which is given out of duty, at the proper time and place, to a worthy person, and without expectation of return is considered to be charity in the mode of goodness.” Thus charity given in the proper place is called sāttvika. And above this charity in goodness is transcendental charity, in which everything is sacrificed for the sake of the Supreme Personality of Godhead. Vāmanadeva, the Supreme Personality of Godhead, had come to Bali Mahārāja for alms. How could one get such an opportunity to give charity? Therefore, Bali Mahārāja decided without hesitation to give the Lord whatever He wanted. One may get various opportunities to lay down his life on the battlefield, but such an opportunity as this is hardly ever obtained.
