Sri:

Swamy,
According to adiyen’s remembrance , from devareer’s upanyasam, the marriage ritual , “Dhruva Nakshtra sighting” , Veda points moon as the landmark for shining star ✨ Dhruv.

The explanation given:
Veda gives easier access to the couple to find Dhruva nakshatra by stating moon as the landmark.

While Technically correct:
Will be some co-ordinate with latitude & longitude or yojana distance etc. This is more precise but difficult to understand for human.

What strategy devareer adopt to answer a specific question:

To make readers/listeners understand? or
To be precise ?
Or
Strike balance between the two?
