Bhagavad Gita Verses on Success & Excellence in Work

बुद्धियुक्तो जहातीह उभे सुकृतदुष्कृते। तस्माद्योगाय युज्यस्व योगः कर्मसु कौशलम्॥

Endowed with wisdom and evenness of mind, one casts off in this life both good and evil deeds; therefore, devote yourself to Yoga; Yoga is skill in action.

तस्मादसक्तः सततं कार्यं कर्म समाचर। असक्तो ह्याचरन्कर्म परमाप्नोति पूरुषः॥

Therefore, without attachment, always perform the actions that should be done; for by performing actions without attachment, one reaches the Supreme.

कर्मणैव हि संसिद्धिमास्थिता जनकादयः। लोकसंग्रहमेवापि संपश्यन्कर्तुमर्हसि॥

Janaka and others attained perfection indeed through action alone; even with the intention of protecting the masses, you should perform action.

यतः प्रवृत्तिर्भूतानां येन सर्वमिदं ततम्।स्वकर्मणा तमभ्यर्च्य सिद्धिं विन्दति मानवः॥

He from whom all the beings have evolved and by whom all this is pervaded, worshipping Him with his own duty, one attains perfection.
