न च विद्यासमो बन्धुः

न च विद्यासमो बन्धुर्न च व्याधिसमौ रिपुः।
न चापत्यसमः स्नेहो न च दैवात्परं बलम्‌॥
na ca vidyāsamo bandhurna ca vyādhisamau ripuḥ |
na cāpatyasamaḥ sneho na ca daivātparaṁ balam ||
There is no relative (well-wisher) equal to knowledge, no enemy as bad as disease;
No affection is equal to that for a child and  there is no power greater than that of God (destiny?).

यो यस्य हृद्यो न हि तस्य दूरः

गिरौ कलापि गगने पयोधौ लक्ष्यान्तरेऽर्कश्च जलेषु पद्मम्‌।
इन्दुर्द्विलक्षे कुमुदस्य बन्धुर्यो यस्य हृद्यो न हि तस्य दूरः॥
girau kalāpi gagane payodhau lakṣyāntare’rkaśca jaleṣu padmam |
indurdvilakṣe kumudasya bandhuryo yasya hṛdyo na hi tasya dūraḥ ||
The peacock is in the mountain and the clouds in the sky; the sun is at the distance of a thousand thousand yojanas and the lotus is in the water,
The moon is two hundred thousand yojanas away from its friend, the lily; what is dear to
one’s heart is not far away.

परोऽपि हितवान् बन्धुः

परोऽपि हितवान् बन्धुः बन्धुरपि अहितः परः।
अहितो देहजो व्याधिः हितम् आरण्यमौषधम्॥
—हितोपदेशः
paro’pi hitavān bandhuḥ bandhurapi ahitaḥ paraḥ|
ahito dehajo vyādhiḥ hitam āraṇyamauṣadham||

A person who is not related to us (stranger) but who helps us in difficulty is [indeed] our relative. Similarly, a relative who does us ill should be considered a stranger. This is just like our own body’s disease, which is an stranger (enemy) to us, while a medicinal plant that grows in a forest (elsewhere) does good to us!
