10.20.33

शरदा नीरजोत्पत्त्या नीराणि प्रकृतिं ययु: । भ्रष्टानामिव चेतांसि पुनर्योगनिषेवया ॥ ३३ ॥

śaradā nīrajotpattyā nīrāṇi prakṛtiṁ yayuḥ bhraṣṭānām iva cetāṁsi punar yoga-niṣevayā

śaradā
by the effect of the autumn season
nīraja
the lotus flowers
utpattyā
which regenerates
nīrāṇi
the bodies of water
prakṛtim
to their natural state (of cleanliness)
yayuḥ
returned
bhraṣṭānām
of those who are fallen
iva
just as
cetāṁsi
the minds
punaḥ
once again
yoga
of devotional service
niṣevayā
by practice

The autumn season, which regenerated the lotus flowers, also restored the various bodies of water to their original purity, just as the process of devotional service purifies the minds of the fallen yogīs when they return to it.
