Aditi is a mysterious goddess. Although She is mentioned several times in the Rig Veda, She is not described nor given much of a personality. We do know, however, that She is the mother of the Adityas and of the great god Indra. Aditi is also the mother of the Vamana Avatar of Vishnu. Strangely though, She does not seem to have a male consort.
Aditi is very much a mother figure, an is often asked by petitioners for Her guidance and protect, as well as to bring wealth and happiness.
Aditi's card differs slightly from the traditional Hierophant in that it is usually a card of strict and unquestioning tradition, whereas Aditi holds tradition within Herself and causes it to bend to the current need. It is a card of both the form and substance of tradition. Aditi, as the mother of the gods, asks for tradition to be examined and followed if it is valid. There are still aspects of social approval and conformity to this card though, as tradition can not be thrown away entirely with risking social disapproval.
Reversed, this card represents an openness to innovative and new ideas. There is a desire to stand out and be different from what is social acceptable. Depending on the surrounding cards, this is either done as a way to fix an unsustainable situation/tradition or as a way to act out against society.
