The One who is Possibility
Devi Kaalika is the path of possibilities. He who walks in her path, shall find her opening random possibilities that lead to a Pre-destined end.
She is known to project difficulties for quick burning of karma and then accelerate the Sadhaka very rigoursly.
There is an illusion of freewill, as she plays with the Sadhaka, but she has already determined his perfect end to the the chosen path.
