Bhagavad Gita 12.16

अनपेक्ष: शुचिर्दक्ष उदासीनो गतव्यथ: ।
सर्वारम्भपरित्यागी यो मद्भक्त: स मे प्रिय: ॥

anapekṣa: śucir-dakṣa udāsīno gatavyatha:
sarvārambha-parityāgī yo mad-bhakta: sa me priya: – 16

The devotee who is free from expectations, pure outwardly and inwardly, efficient, indifferent and impartial, free of any strong afflictions, who keeps away all sense of doership in all that he does or proposes to do, is dear to Me (the Supreme).
