Sakti and Siva
Right now also each part of your existence is active. All limbs of the body, all faculties of the mind, all levels of the consciousness are active energies. Sakti is known to you in many forms.
Siva is inactive and idle.
The world is the extrovert expression of Sakti. When Sakti moves toward Siva it becomes awareness. When Sakti becomes one with Siva World disappears.
You are aware of Sakti as much as your conscious mind is awakened.
Full awareness leads one to the appearance of Sakti from Siva and disappearance of Her in Him again.
