Shakti can be seen as the "mother" of all things in the Universe, as Shiva can be seen as the "father" of all things. This is a very easy concept to wrap your brain around if you envision them as 'beings'....god and goddess with attributes. However, they truly have no attributes, except for Energy and Matter.

The same electricity that makes your coffee can also kill you. The knife cares not that it cut your finger rather than your dinner. Shiva and Shakti have no 'personality' per se; they have only a usefulness, such as electricity and knives. It is up to the human to channel that usefulness in a useful way.

To be "invoked" of Shakti means to be full of that Energy which begat all things. To fully carry the burden of "mother of all" one must know how to channel that Energy of Shakti into a purpose: create! And what's the use of creating something useless? If it's not helpful, necessary, or beautiful, it's not a positive use of Shakti's powers. Creating is what she does best.

But wait! What about Kali-Ma? The Energy of Destruction? Isn't she a facet, an angle, a personality of Shakti? Truly Mother Kali cannot be attributed to the 'Motherhood of all?" Ah, yes, but Shakti cannot create infinitely without infinite space and matter to create with. Hence, the need for the Goddess of destruction and the Goddess of Creation to be one and the same, even if different sides of the same coin. Life, Death, Rebirth, Life Death.....can't have Death and Destruction without it being connected to Energy....Shakti.

Hail Shakti...in all her facets....as we all send positive thoughts to our Mothers...

Om, namah Shakti, Om.
