My sister is needed first for the auspicious start; no one else can fulfill her specific role. Send the other person to Mumbai to call Aunt Jamnabai.

This couplet beautifully expresses the indispensable role of a specific person, 'Beni', for any new beginning or auspicious occasion. It highlights that her presence is absolutely crucial, and no one else can truly fulfill her unique responsibilities. It's like saying, 'Only Beni can do this job, no one else comes close.' In contrast, the second part of the couplet suggests that for a different task, like inviting Aunt Jamnabai from Mumbai, someone else can be sent. This clearly distinguishes between a person whose presence is vital and irreplaceable, and a task that can be delegated. It's a sweet way to acknowledge someone's unique importance.
