Parvati.

Since a while, Parvati was most important Godess of Hindu spirituality for me, She still is.

Parvati- the mother of Ganesha and Kartikeya.

Parvati is also known as Gauri or Shakti.

She is considered the most powerful Goddess in the Hindu religion.

All the other goddesses are considered either avatars of Parvati or manifestations of her.

Her famous and most worshipped incarnations include Durga, Kali and Chandi.
