Why did Lord Shiva drink his wife's milk? What is the exact story behind this incident? Husband wife theory doesn't apply here because the relationship between Matter and Wave, consciousness and energy is what is depicted by Shiva and Shakti. If you want to understand the depth of it you will have to go beyond the physical relationship of human beings built by society. It's a divine cosmic play that can be seen only when a drop decides that he is a part of the ocean and not separate as some drop…. The story is of the time of the churning of the Ocean. Goddess Lakshmi had disappeared from Earth due to a curse and had gone into the ocean. To bring her back, both Devas and Asura used a huge mountain and Vasuki snake to churn the ocean. They also wanted to get Nectar which would make them immortal. Here see how it looks: Lord Vishnu in order to give a stable base to the mountain took Avatar of a tortoise and held the mountain on his back. Now the task began. One by one amazing things started coming out and Devas and Asuras kept dividing them among themselves. Then trouble began, the most dangerous poison of the universe called Halahal appeared! Nobody had a clue on what to do, the whole world started getting decaying. Both parties prayed to Shiva to save them. Shiva took the bowl of poison and drank it up! However since it was very strong, it started effecting Shiva too! Shiva is inert Matter, pure consciousness pure bliss: the absolute! However when negative energy from whole Universe startes attacking it, it can start creating imbalance if not kept stable. So Shiva kept it concentrated in his throat and got the name of Neelkanth Mahadev (blue throat one). It started hurting him too much although and he needed extra energy: he was Pure Consciousness, he needed Shakti! Then the Primordial force of the World: Energy in its purest form, Devi took the form of a Blue complexioned Goddess called Tara. She made Shiva drink her milk thus removing the pain due to Halahal. She is second among the 10 Mahavidyas. No she is not called Parvati, but called Tara. If you want to feel her Aura, go to the Tarapeeth temple in West Bengal, She is much present there if you have devotion. It's said that nobody returned empty handed from her doors… When Imbalance occurs in nature, Supreme Energy: Prakriti herself comes to fix it. That's what Maa Tara stands for….
