11.20.23

निर्विण्णस्य विरक्तस्य पुरुषस्योक्तवेदिन: । मनस्त्यजति दौरात्म्यं चिन्तितस्यानुचिन्तया ॥ २३ ॥

nirviṇṇasya viraktasya puruṣasyokta-vedinaḥ manas tyajati daurātmyaṁ cintitasyānucintayā

nirviṇṇasya
of one who is disgusted with the illusory nature of the material world
viraktasya
and who is therefore detached
puruṣasya
of such a person
ukta-vedinaḥ
who is guided by the instructions of his spiritual master
manaḥ
the mind
tyajati
gives up
daurātmyam
the false identification with the material body and mind
cintitasya
of that which is contemplated
anucintayā
by constant analysis

When a person is disgusted with the temporary, illusory nature of this world and is thus detached from it, his mind, guided by the instructions of his spiritual master, considers again and again the nature of this world and eventually gives up the false identification with matter.
