Bhagavad Gita on Detachment

BG 2.47

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन।

Your right is only to work, but not to its results; do not let the results of action be your motive, nor let your attachment be to inaction.

BG 2.48

योगस्थः कुरु कर्माणि सङ्गं त्यक्त्वा धनञ्जय।

Perform action, O Arjuna, being steadfast in Yoga, abandoning attachment and balanced in success and failure; evenness of mind is called Yoga.

BG 2.50

बुद्धियुक्तो जहातीह उभे सुकृतदुष्कृते।

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.

BG 5.10

ब्रह्मण्याधाय कर्माणि सङ्गं त्यक्त्वा करोति यः।

He who does actions, offering them to Brahman and abandoning attachment, is not tainted by sin, just as a lotus leaf is not tainted by water.

BG 12.16

अनपेक्षः शुचिर्दक्ष उदासीनो गतव्यथः।सर्वारम्भपरित्यागी यो मद्भक्तः स मे प्रियः

He who is free from wants, pure, expert, unconcerned, and free from pain, renouncing all undertakings and commencements, he who is devoted to Me is dear to Me.

BG 2.71

विहाय कामान्यः सर्वान्पुमांश्चरति निःस्पृहः।

That person attains peace who, abandoning all desires, moves about without longing, without the sense of ownership, and without egoism.
