Lord Shiva and Goddess Shakthi

In the Tantric cosmology, the whole universe is perceived as being created, penetrated and sustained by two fundamental forces, which are permanently in a perfect, indestructible union. These forces or universal aspects are called Shiva and Shakti.

The tradition has associated to these principles a form, respectively that of a masculine deity and that of a feminine one. Accordingly, Shiva represents the constitutive elements of the universe, while Shakti is the dynamic potency, which makes these elements come to life and act.  

Typically, Shakti is associated with Shiva. Mother Shakti or Durga is the energy aspect of the Lord. Without Shakti, Shiva has no expression; and, without Shiva, Shakti has no existence. Shakti is identical with Shiva. Lord Shiva is only the Silent Witness. He is motionless, absolutely changeless. He enjoys the cosmic play and Shakti does everything.

Siva is omnipotent, impersonal, inactive. He is pure consciousness. Shakti is dynamic. The power, or active aspect, of the immanent God is Shakti. Shakti is the embodiment of power. She is the eternal consort of Lord Shiva.

There is no difference between Shiva and Shakti. Shakti or Durga is co-existent with Shiva. Just as you cannot separate heat from fire, so also you cannot separate Sakti from Shiva, the Generator of Shakti. Note that Shiva is not creator of Shakti but he only generates. Shiva is transcendent divinity and Shakti is the one who made him that. Siva and Sakti are one. Siva is always with Sakti. They are inseparable. Worship of Durga or Parvati or Kali is worship of Lord Siva. Worship of God Shiva is Worship of Goddess Shakti.
