रागी कर्मफलप्रेप्सुर्लुब्धो हिंसात्मकोऽशुचिः। हर्षशोकान्वितः कर्ता राजसः परिकीर्तितः ॥

rāgī karma-phala-prepsur lubdho hinsātmako ‘śhuchiḥ harṣha-śhokānvitaḥ kartā rājasaḥ parikīrtitaḥ

Impassioned, desiring to obtain the fruit of actions, greedy, harmful, impure, moved by joy and sorrow, such an actor is pronounced passionate.

In plain words: A doer ruled by passion is eager for rewards, greedy and willing to harm. They are not clean in heart and are tossed around by joy and sorrow.
