Srimad Bhagavatam 10.25.4

10.25.4

यथाद‍ृढै: कर्ममयै: क्रतुभिर्नामनौनिभै: । विद्यामान्वीक्षिकीं हित्वा तितीर्षन्ति भवार्णवम् ॥ ४ ॥

yathādṛḍhaiḥ karma-mayaiḥ kratubhir nāma-nau-nibhaiḥ vidyām ānvīkṣikīṁ hitvā titīrṣanti bhavārṇavam

yathā
as
adṛḍhaiḥ
which are inadequate
karma-mayaiḥ
based on fruitive activity
kratubhiḥ
by ritual sacrifices
nāma
in name only
nau-nibhaiḥ
which serve as boats
vidyām
knowledge
ānvīkṣikīm
spiritual
hitvā
abandoning
titīrṣanti
they try to cross beyond
bhava-arṇavam
the ocean of material existence

Their taking shelter of Kṛṣṇa is just like the foolish attempt of men who abandon transcendental knowledge of the self and instead try to cross over the great ocean of material existence in the false boats of fruitive, ritual sacrifices.
