SB 4.23.21
deham vipannakhila-cetanadikam
patyuh prthivya dayitasya catmanah
alaksya kiñcic ca vilapya sa sati
citam atharopayad adri-sanuni
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When Queen Arci saw that her husband, who had been so merciful to her and the earth, no longer showed symptoms of life, she lamented for a little while and then built a fiery pyre on top of a hill and placed the body of her husband on it.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After seeing all the life symptoms in her husband stop, the Queen lamented for a while. The word kiñcit means “for a little while.” The Queen was completely aware that her husband was not dead, although the symptoms of life — action, intelligence and sense perception — had ceased. As stated in Bhagavad-gita (2.13):
dehino ’smin yatha dehe
kaumaram yauvanam jara
tatha dehantara-praptir
dhiras tatra na muhyati
“As the embodied soul continually passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. The self-realized soul is not bewildered by such a change.”
When a living entity transfers from one body to another, a process generally known as death, a sane man does not lament, for he knows that the living entity is not dead but is simply transferred from one body to another. The Queen should have been afraid of being alone in the forest with the body of her husband, but since she was a great wife of a great personality, she lamented for a while but immediately understood that she had many duties to perform. Thus instead of wasting her time in lamentation, she immediately prepared a fiery pyre on top of a hill and then placed the body of her husband on it to be burned.
Maharaja Prthu is described here as dayita, for not only was he the king of the earth, but he treated the earth as his protected child. Similarly, he protected his wife also. It was the duty of the king to give protection to everyone, especially to the earth or land which he ruled, as well as the citizens and his family members. Since Prthu Maharaja was a perfect king, he gave protection to everyone, and therefore he is described here as dayita.
