चतुर्विधा भजन्ते मां जनाः सुकृतिनोऽर्जुन। आर्तो जिज्ञासुरर्थार्थी ज्ञानी च भरतर्षभ ॥

chatur-vidhā bhajante māṁ janāḥ sukṛitino ’rjuna ārto jijñāsur arthārthī jñānī cha bharatarṣhabha

Fourfold in division are the righteous ones who worship me, O Arjuna; the suffering, the seeker for knowledge, the self-interested and the wise, O Lord of the Bhâratas.

In plain words: Krishna says four kinds of good people worship him: those who are suffering, those who want knowledge, those who want something for themselves, and the wise.
