Sharing with others, serving others, this is the main Sutra of Vidya, its genuine expression.
Education is rendered noble when the spirit of service is inculcated.
The service rendered must be free of the slightest trace of narrow selfishness. That is not enough. The thought of service should not be marred by the desire for something in return. You have to perform the service as you would perform an important Yajna or Sacrifice. Only thus can they justify their status as 'noble men,' sajjana.
