11.14.26

यथा यथात्मा परिमृज्यतेऽसौ मत्पुण्यगाथाश्रवणाभिधानै: । तथा तथा पश्यति वस्तु सूक्ष्मं चक्षुर्यथैवाञ्जनसम्प्रयुक्तम् ॥ २६ ॥

yathā yathātmā parimṛjyate ’sau mat-puṇya-gāthā-śravaṇābhidhānaiḥ tathā tathā paśyati vastu sūkṣmaṁ cakṣur yathaivāñjana-samprayuktam

yathā yathā
as much as
ātmā
the spirit soul, the conscious entity
parimṛjyate
is cleansed of material contamination
asau
he
mat-puṇya-gāthā
the pious narrations of My glories
śravaṇa
by hearing
abhidhānaiḥ
and by chanting
tathā tathā
exactly in that proportion
paśyati
he sees
vastu
the Absolute Truth
sūkṣmam
subtle, being nonmaterial
cakṣuḥ
the eye
yathā
just as
eva
certainly
añjana
with medicinal ointment
samprayuktam
treated

When a diseased eye is treated with medicinal ointment it gradually recovers its power to see. Similarly, as a conscious living entity cleanses himself of material contamination by hearing and chanting the pious narrations of My glories, he regains his ability to see Me, the Absolute Truth, in My subtle spiritual form.
