मयि चानन्ययोगेन भक्तिरव्यभिचारिणी ।विविक्तदेशसेवित्वमरतिर्जनसंसदि॥
mayi cānanya-yogena bhaktir avyabhicāriṇīvivikta-deśa-sevitvam aratir jana-sansadi
Word by word
The verse says
— unbroken devotion to me, joined to nothing else; a liking for quiet places; no taste for crowds of people —
In plain words
Two of these three are about where you prefer to be.
A liking for solitary places, and aratir jana-saṃsadi — no pleasure in large gatherings.
It is the most introverted line in the book, and it sits in the middle of a list about how to behave toward others.
Where you've felt this · in friendship
Your friend will stay for three hours at a dinner with four people and leave a party of forty after twenty minutes. She is not shy and she is not unfriendly. The second room simply does not give her anything, and she stopped apologising for that in her thirties.
Going deeper
A preference for quiet is listed as knowledge, which is worth both taking seriously and holding carefully.
Taken straight, it says that the capacity for solitude belongs with patience and honesty on the list of things that indicate understanding. There is a reason for that which anybody can verify: a great deal of what people do in groups is maintenance of how they are seen, and this list opened by naming the absence of that need.
So the dislike of crowds is downstream of the first item rather than a separate temperament.
It needs holding carefully, though, because it can be used to dignify simple avoidance. The same list requires doing no harm, patience and service, none of which can be practised alone. What is being described is somebody who does not need the room, not somebody who cannot manage it.
