Bhagavad Gita 7.16
O Arjuna! The righteous who worship Me are grouped in stages: first, those who suffer, next those who desire knowledge, then those who thirst after truth, and lastly those who attain wisdom.
चतुर्विधा भजन्ते मां जनाः सुकृतिनोऽर्जुन।
आर्तो जिज्ञासुरर्थार्थी ज्ञानी च भरतर्षभ॥caturvidhā bhajante māṃ janāḥ sukṛtino'rjuna|
ārto jijñāsurarthārthī jñānī ca bharatarṣabha||
