The author David Frawley describes Bala Tripura Sundari as:
Tripura Sundari is often represented as a girl of sixteen years age. As such she is called "sixteen" (shodashi) or "the young girl" (bala). At this stage of a woman's life, the delight aspect of her existence is most pronounced. Her nature is to play, to seek new experience, and to charm others to her. Her innocence attracts all to her that is true and good.As a young girl Sundari guides the young aspirant on the path, representing the innocence of initial aspiration that we should preserve throughout our entire journeying into the infinite.References
