Todaay's Suubhashita.

अर्थोपचयविज्ञानं अस्ति यस्य स पण्डितः |
सरः सलिलसपूर्णं  आश्रयन्ति विहङ्गमाः  ||

अर्थ -   अर्थशास्त्र  (धन और संपत्ति के  अर्जन और संरक्षण के वैज्ञानिक
 नियम आदि )   मे जो व्यक्ति पारङ्गत होता है वही वास्तव मे विद्वान्
कहलाता है | जिस तरह  से  जल से भरा हुआ एक सरोवर  सैकडों पक्षियों
को आश्रय देता है उसी तरह् एक अर्थशास्त्री  भी एक देश  को संपन्न बनाने
मे अपनी योग्यता का सदुपयोग करता है |

(इस सुभाषित मे अर्थशास्त्र को विज्ञान के समतुल्य मान कर तथा एक
अर्थशास्त्री की तुलना एक सरोवर से कर उसकी समाज मे उपयोगिता  को
रेखांकित किया गया है | )

Arthopachayavigyaanam asti yasya sa panditah.
Sarah salilasapoornam aashryanti vihangamaah.

Arthopachaya = creation of wealth.   Vigyaanam =  a science.
Asti = exists, has.     Yasya = whose.    Sa = he.  
Panditah = a learned  person.    Sarah = a lake.
Salila = water.    Sapoorna = filled with.    Aashryanti =
provide shelter and support.   Vihangamaaah = birds.

i.e.     A person who is an expert in the science of creation, augmentation
and preservation of wealth (Economics)is considered a real scholar.
Just like a big lake overflowing with water, which provides sustenance and
shelter to numerous birds, an Economist also uses his expertise in uplifting
the economy of a country.

(In this Subhashita by equating Economics with Science, and by using a
simile of a big lake for an economist,  the author has emphasized the role
of an Economist in a country's economy.)
