B.G 7.27

इच्छाद्वेषसमुत्थेन द्वन्द्वमोहेन भारत। सर्वभूतानि संमोहं सर्गे यान्ति परन्तप ॥२७॥

O Bharata, Arise from desire and aversion caused by the delusion of duality. O chastiser of foes, all beings are subject to intense delusion from the time of creation.

Gīta Bhāshya 7.27

'dvandva-moha' - delusion of experienced topics and objects caused by pleasure and pain; 'sarge' - time from the beginning of creation; Along with the corporeal body comes the desire and other defects. However, previously there was only ignorance.

द्वन्द्वमोहेन सुखदुःखादिविषयमोहेन। इच्छाद्वेषयोः प्रवृद्धयोः न हि किञ्चित् ज्ञातुं शक्यम्। कारणान्तरम् एतत्। सर्गे सर्गकालं आरभ्यैव। शरीरे हि सति इच्छादयः। पूर्वं तु अज्ञानमात्रम् ॥२७॥

The word 'dvandva-moha' i.e. delusion caused by duality, refers to the delusion of experienced topics and objects caused by pleasure and pain. Because of tendencies driven by desire and aversion, it becomes impossible to know anything. This is another cause. The word 'sarge' refers to the time from the beginning of creation. Along with the corporeal body comes the desire and other defects. Previously, however, there was only ignorance.
