Please read something VERY interesting I found about Kala and Ajna:
http://www.jinalaya.com/jainism/ajiva.htm
To be as simple as possible [because my english aren't good sadly], there are many names related with the characters of the game:
Ajna is related with the name
Ajiva.
Ajiva is the universal name of five Astikaya.
Astikaya is Asti & Kaya. Asti means space, body or mode and Kaya means collection. So Astikaya means a collection of spaces or regions.
However Ajiva is non-sentient, without a soul.
The one who is sentient with soul is Jiva.
Both Jiva and Ajiva are crucial elements for the order of universe.
If we connect this with Anja ability to have incarnations to her side and being an empty boby, this is connected with the theory of emptiness I mentioned already in other thread I created.
Ajna is trying to fix the universe by connecting different type of regions to her emptiness.
However Kala, isn't like the other Astikaya.
Specificaly is Marana Kala.
3. Marana kala - The end of life is called marana kala.
