shashthi (sixth)
Today celebrate the sixth day of Navratni. Saraswati Awahan (invocation), first day of Saraswati Puja.
Saraswati is the goddess of knowledge, music, arts and science. A goddess of learning and a guardian of the earth.
I particularly like this list of names from the Wikipedia article:
She is also addressed as Sharada (the one who loves the autumn season), Veena pustaka dharani (the one holding books and a Veena), Vaakdevi, Vagdevi, Vani (all meaning “speech”), Varadhanayagi (the one bestowing boons) and many other names.
