Jñāneśvarī (commentary on the Bhagavadgītā) 2.234

2.234

nehābhikramanāśo 'sti pratyavāyo na vidyate
svalpam apy asya dharmasya trāyate mahato bhayāt
karmādhāreṃ rāhāṭije |
parī karmaphaḷa na nirīkṣije |
jaisā maṃtrajñu na badhije |
bhūtabādhā ||

One acts relying on action, / yet one does not look for the fruit of action, / just as a knower of mantras is not afflicted / by the affliction of evil spirits.
