yadākṣaiś caritān dhyāyan karmāṇy ācinute’sakṛt |
sati karmaṇy avidyāyāṁ bandhaḥ karmaṇy anātmanaḥ ||
(Śrīmad Bhāgavatam: 4.29.78)
“[How is the mind the cause of saṁsāra?] When one repeatedly performs karmas thinking of objects attained [previously] by the senses, then, since karma [i.e., a karmic reaction] is present and thus [also] avidyā [i.e., the underlying basis of karma is also present], bondage to the karma of the non-ātmā occurs.”
