Aditi in the Veda represents the concept of wholeness (pūrņatva). Here she is represented as the Queen of the Eternal Order. Recall that in RV (1.89.10), she is described as “All that is born and what is to be born”.
The Mighty Mother of those whose sway is just,
Queen of Eternal Order (ŗta), we call for help,
Aditi, the great Ruler, undecaying,
Far-expanding, good Protectress, gracious Guide. SYV (21.5)
