Whenever I see Ashwini and Bhavani I am reminded of this song. This song is about how a woman inspite of not giving birth became a mother to someone and on the other hand about someone who despite giving birth could never become a mother.
Ashwini without giving birth to Sai became her mother but Bhavani despite giving birth to Devyani could never really become her mother. It is in Telugu, so I tried translating it for you people.

kantene amma ani ante ela
how can you name a someone a mother just by giving birth
karuninche prathi devatha amme kada
any woman who shows kindness and love is a mother
kanna amme kada
she is equal to a mother who gave birth
kantene amma ani ante ela?
how can you name a someone a mother just by giving birth
Kaduputipi leni amma bomme kada
a mother who has no motherly feelings is just a statue/toy
Rati bomme kada
She is just an iron statue
Kanakana lade endaku sirasu madina
Even if she is burning under the hot scorching sun
Manaku tana needanu andinche chette amma
A mother is the one who gives us shade like a tree
Charedu neellina tanu dachukoka
Without saving even an ounce of water for herself
Jagatiki sarvasvam arpinche mabbe amma
A mother is the cloud who gives her everything to the world
Aa ammalane minchina ma ammaku
My mother is above all such mothers
Runam tirchukolenu a janmaku
I can never repay her in any number of births
Enno antastulu ga edigi poyina
A building may grow to any number of floors
Medakunna asalu uniki a punadhi pine
But its existence is due to its foundation
Sirula jallulo nityam paravasinchina
Even though one is enjoying all the time with wealth
Maguva jeevana safalyam matrutvam lone
A woman is complete only by being a mother
Prati talliki mamakaram paramartham
Love and affection(mamta) is the main essence of any mother
Adi leni ahankaram vyartham vyartham
Arrogance without that is useless.
