Oh Arjuna! Four types of virtuous people worship Me: the afflicted, the inquirer, the one who desires wealth, and the knower, oh bull of the Bharata dynasty!

The sukṛtinaḥ (doers of good karma) are divided into four according to motivation: ārta (afflicted, seeks relief), jijñāsu (inquirer, seeks to know), arthārthī (desires artha — wealth/purpose), jñānī (knower, sage).

All bhajante (worship, cultivate relationship with) Kṛṣṇa. The difference is spiritual maturity, not moral rectitude.
