Bhagavad Gita · Chapter 7: Knowledge and Realization
Bhagavad Gita 7.27
इच्छाद्वेषसमुत्थेन द्वन्द्वमोहेन भारत ।
सर्वभूतानि संमोहं सर्गे यान्ति परन्तप ॥
icchādveṣasamutthena dvandvamohena bhārata | sarvabhūtāni saṃmohaṃ sarge yānti parantapa ||
Through the delusion of the pairs of opposites, which arises from desire and aversion, Arjuna, all beings fall into confusion from birth.
Modern context
Why are we all confused? Krishna traces it to two forces present from birth: wanting and not wanting. Every experience is sorted at once into 'I like this' and 'I don't like this', and our whole lives get organized around chasing the first and avoiding the second. This sorting is so automatic we do not notice it. But it splits the world into opposites and keeps us swinging between them. Seeing the mechanism is the first step out of it.
