Tirukkural-On Virtue-On The Blessing Of Children-Kural 70

Makanthandhaikku aattrum udhavi ivanthandhai
Ennottraan kolenum sol.

The way of showing filial devotion is to make others exclaim within the hearing of the father what penance the father must have performed to beget such a son.

A son's duty to the father is to behave in such a way that people who look on his exploits praise his father for his penance in siring such a son.

The bible says:
'A wise son shall make a glad father but a foolish son is the heaviness of his mother'.

The reference here is certainly to son as well as daughter. Parimelalagar errs again here, by taking Valluvar's meaning literally and narrowly to refer to a son only. And so also, it is the father as well as the mother, who will be praised by others for begetting such a son or daughter. For did not Thiruthakka Thevar say in Jeevaka Chintamani, when Jeevakan had acquitted himself creditably on the battlefield.

Semalai payandha nattraai
Seithavam udayaar yenbaar
Yemalaithavam Saeithaal kol
Yeidhuvam yaamum yenbaar

The idea here is definitely adopted from Valluvar's Kural.
