10.5.23

दिष्टय‍ा भ्रात: प्रवयस इदानीमप्रजस्य ते । प्रजाशाया निवृत्तस्य प्रजा यत् समपद्यत ॥ २३ ॥

diṣṭyā bhrātaḥ pravayasa idānīm aprajasya te prajāśāyā nivṛttasya prajā yat samapadyata

diṣṭyā
it is by great fortune
bhrātaḥ
O my dear brother
pravayasaḥ
of you whose age is now quite advanced
idānīm
at the present moment
aprajasya
of one who did not have a son before
te
of you
prajā-āśāyāḥ nivṛttasya
of one who was almost hopeless of getting a son at this age
prajā
a son
yat
whatever
samapadyata
has been gotten by chance

My dear brother Nanda Mahārāja, at an advanced age you had no son at all and were hopeless of having one. Therefore, that you now have a son is a sign of great fortune.
