Happy Mother's Day to all kinds of mothers high and low, near and far, nurturing or not, loved or not.
Mothers of all creatures and humans provide the birth opportunity for cultivation of noble qualities and fulfillment of obligations. How unlivable this world would be without the nurturing investment by mothers.
Most of the Puranas are dedicated to male deities, except for the Devi Purana. There it is proposed that God is a female, as the primal nurturing Person, even as the one who nurtures God when God is proposed as a male.
Existentially when a male looks to the right and to the left, he sees females. These appear spontaneously. He has to figure how they arrived in the environment but as to their purpose, that is self-evident. They are the nurturing factor in the creation. That is an existential mystery!
