मातुश् चित्त क्षोभ भयात् कुल्यम् अल्प सत्त्वं छात्रं च लक्षण्यम् उपनिदध्यात् ॥
He shall keep as a representative of the prince one who is of the same family, of little valour and of beautiful appearance, lest the mother's mind may be agitated with wild apprehensions.
english translation
mAtuz citta kSobha bhayAt kulyam alpa sattvaM chAtraM ca lakSaNyam upanidadhyAt ॥
