mana eva manuṣyāṇaṁ kāraṇaṁ bandha-mokṣayoḥ
mana eva manuṣyāṇaṁ kāraṇaṁ bandha-mokṣayoḥ |
bandhāya viṣayāsaktaṁ muktyai nirviṣayaṁ smṛtam ||
(Maitrāyaṇīya Upaniṣad: 6.34.11)
“For human beings, the mind alone is the cause of bondage and mokṣa. A mind that is attached to sense objects is regarded as the cause of bondage, and a mind uninvolved with the sense objects is [regarded as] the cause of liberation.”
