इच्छाद्वेषसमुत्थेन द्वन्द्वमोहेन भारत।सर्वभूतानि संमोहं सर्गे यान्ति परन्तप॥
icchā-dveṣa-samutthena dvandva-mohena bhāratasarva-bhūtāni sammohaṃ sarge yānti parantapa
Word by word
The verse says
From wanting and from hating, from the confusion of opposites, Arjuna, every being goes into a fog from the moment it is born.
In plain words
Dvandva — the pairs. Hot and cold, praise and blame, winning and losing.
The confusion is not that the pairs exist. It is that we sort everything into them before we have looked properly.
And the verse says this starts at birth, not at some later fall from grace.
Where you've felt this · in relationships
You meet someone at a wedding and inside a minute you have decided whether you like them. The decision arrives before any evidence does, and everything they say afterwards gets filed under it. If they say something dull and you had decided yes, it was modesty. If you had decided no, it was proof.
Going deeper
Wanting and hating are being described as one mechanism, not two.
Icchā and dveṣa — pulling toward and pushing away — run before thought does. Something appears, it is sorted into toward or away, and only afterwards do we produce reasons. The reasons are often excellent. They are also downstream.
The word sarge, from birth, is doing quiet work in the line. This is not a corruption picked up from bad company or a wrong turn taken somewhere. It is the operating condition of a creature that has to decide quickly what to eat and what to run from.
What that buys you is a small and usable gap. Next time a strong first impression arrives fully formed with its reasons already attached, you know something about the order those two things came in. It does not make the impression wrong. It does mean it has not been examined yet.
