The parents only are the best of friends. The wife is merely a soil for sowing seeds. The son is only one's seed. The brother is an enemy. The friend or companion wants to have his palms oiled if he is to continue so. One's own self enjoys or suffers one's happiness or misery.
माता पिता बान्धवानां वरिष्ठौ भार्या जरा बीजमात्रं तु पुत्रः। भ्राता शत्रुः क्लित्रपाणिर्वयस्य आत्मा ह्येकः सुखदुःखस्य भोक्ता॥
