SB 6.14.29

athaha nrpatim rajan
 bhavitaikas tavatmajah
harsa-soka-pradas tubhyam
 iti brahma-suto yayau
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Thereafter, the great sage told the King, “O great King, now you will have a son who will be the cause of both jubilation and lamentation.” The sage then left, without waiting for Citraketu’s response.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The word harsa means “jubilation,” and soka means “lamentation.” The King was overwhelmed with joy when he understood that he would have a son. Because of his great jubilation, he could not actually understand the statement of the sage Angira. He accepted it to mean that there would certainly be jubilation because of the birth of his future son, but that he would be the King’s only son and, being very proud of his great wealth and empire, would not be very obedient to his father. Thus the King was satisfied, thinking, “Let there be a son. It does not matter if he is not very obedient.” In Bengal there is a proverb that instead of having no maternal uncle, it is better to have a maternal uncle who is blind. The King accepted this philosophy, thinking that a disobedient son would be better than no son at all. The great sage Canakya Pandita says:
 
ko ’rthah putrena jatena
 yo na vidvan na dharmikah
kanena caksusa kim va
 caksuh pidaiva kevalam
 
“What is the use of a son who is neither a learned scholar nor a devotee? Such a son is like a blind, diseased eye, which always causes suffering.” Nevertheless, the material world is so polluted that one wants to have a son even though he is useless. This attitude was represented in the history of King Citraketu.
