रजोभिः समसंख्याकाः पार्थिवैरिह जंतवः ।
तेषां ये केचनेहंते श्रेयो वै मनुजादयः ॥
rajobhiH samam sankhyaakAH pArthivaiH iha jantavaH ।
teShAm ye kechana ihante shreyo vai manujAdayaH ॥
In this world there are as many beings as particles of dust. Among them only a handful of them are capable of thinking about their own welfare. Mankind is one among them.
