Four Parts

The Bhagavatî Bhavânî is present, as it were, being divided into four parts. 

1. She who is the first and foremost, the excellent Sâttvic Energy, worshipped by all, is always engaged in the preservation of this world. 
2. That part which is engaged in creating this world, is called the Râjasik Energy; and that part which is engaged in destroying the world is called the Tâmasik Energy, and 
3. that part which is the cause of all, Brahmâ, etc., 
4. that Highest S’akti, the Bestower of all desires, is called the fourth S’akti, the Nirgunâ S’akti.
