Saraswati, for what it’s worth, is one of my all-time favourite Goddesses.
I first heard of her in 2004 when I made my first trip to the Sri Narayani Peedam in southern India, an ashram which I have been visiting every since.
Saraswati is actually one of the 3 main Goddesses that the ashram is devoted to (the other two are Lakshmi and Durga).
Saraswati is the Goddess of language, learning and Divine feminine wisdom. As such, she “matches” perfectly with the planet of language, learning and smarts, Mercury.
So if you want to use Mercury retrograde to connect with the Divine, Saraswati is the ideal conduit. I recorded this meditation really as a devotion to Saraswati however I know it’s just right to help anyone through the mayhem of any Mercury retrograde.
