Maa Kali

Kali is considered as the first incarnation of Goddess Durga and is considered a more fierce and aggressive form of Durga. The ferocious Goddess is depicted with disheveled hair, wearing a garland of skulls and holding a demon’s head in one hand and a weapon on the other. Lord Shiva lay himself down in her path to stop her insatiable blood lust, in this case the Shiv Ling is the symbolism of that.
Wishing everyone a very prosperous Diwali
