Bhagavad Gita · Chapter 18: Freedom through Renunciation
Bhagavad Gita 18.27
रागी कर्मफलप्रेप्सुर्लुब्धो हिंसात्मकोऽशुचिः ।
हर्षशोकान्वितः कर्ता राजसः परिकीर्तितः ॥
rāgī karmaphalaprepsurlubdho hiṃsātmako'śuciḥ | harṣaśokānvitaḥ kartā rājasaḥ parikīrtitaḥ ||
A doer who is full of passion, who craves the fruit of action, and who is greedy, harmful, impure, and swayed by joy and sorrow, is declared to be of passion.
Modern context
The rajasic doer is passionate, craves results, is greedy, harms others, and swings between elation and despair. This is a familiar type: the ambitious worker who rides high on success and crashes on failure, who will cut corners or hurt others to get ahead. Energy is not the problem; the craving behind it is.
