Every Hindu is well aware of (male) trinities, but I have also heard that there are female trinities too.
Is that correct?
One can view Lakshmi, Saraswati, and Parvati (Kali) as the female trinity.
They are the wives/female counterparts of Vishnu, Brahma and Shiva, respectively.
The male trinity is essentially incomplete without a female trinity.
The female trinity comprises of Saraswati, Laxmi and Shakti who are the consorts of Brahma, Vishnu and Shiva respectively.
