विषात् अपि अमृतम् ग्राह्यम् अमेध्यात् अपि कांचनम्

इस सुभाषित को सुधर्मा अख़बार में पडा आज तो याद आया. लीजिये आपके लिए पेश ए ख़िदमत है

विषात् अपि अमृतम् ग्राह्यम् अमेध्यात् अपि कांचनम् 

नीचात् अपि उत्तमा विद्या स्त्रीरत्नम दुष्कुलात् अपि ॥

(कौटिल्यस्य नय:) (The wisdom of KauTilya)

viShaat api amRtam graahyam amedhyaat api kaanchanam

neechaat api uttamaa vidyaa, stree ratnam duShkulaat api ||

The meanings of the words are quite self-explanatory. 'amedhya' refers to filth. It is also a word used for excrement. 

If there is nectar in poison, accept it. If there is gold even in filth, retrieve it. If a lowly man has knowledge, wisdom, art or quality, imbibe it. If a woman born to a family of disrepute turns out to be a lady  of high qualities, then she is worthy like a gem.
