7.7.27

एतद्‌द्वारो हि संसारो गुणकर्मनिबन्धन: । अज्ञानमूलोऽपार्थोऽपि पुंस: स्वप्न इवार्प्यते ॥ २७ ॥

etad dvaro hi samsaro guna-karma-nibandhanah ajnana-mulo ’partho ’pi pumsah svapna ivarpyate

etat
this
dvarah
whose door
hi
indeed
samsarah
material existence, in which one suffers threefold miseries
guna-karma-nibandhanah
captivation by the three modes of material nature
ajnana-mulah
whose root is ignorance
aparthah
without factual meaning
api
even
pumsah
of the living entity
svapnah
a dream
iva
like
arpyate
is placed.

Through polluted intelligence one is subjected to the modes of nature, and thus one is conditioned by material existence. Like a dreaming state in which one falsely suffers, material existence, which is due to ignorance, must be considered unwanted and temporary.
