Bhagavad Gita 7.16

चतुर्विधा भजन्ते मां जना: सुकृतिनोऽर्जुन ।
आर्तो जिज्ञासुरर्थार्थी ज्ञानी च भरतर्षभ  ॥

catur-vidhā bhajante māṃ janā: sukṛtino’rjuna
ārto jijñāsur-arthārthī jñānī ca bharatarṣabha – 16

Four kinds of virtuous people worship Me – the afflicted, the enquiring, the one yearning for some specific gain, and the Knower, O great amongst the Bharatas.
