Supreme Consciousness divides in time and space..Shakti divides herself into Nada, Bindu and Bija. Bindu is Shiv and Bija is Shakti. Nada is the relationship between the two. Nada and Bindu are the building blocks of the universe..She who is Tattva is Chinmatra: When she wishes to create, She becomes massive and assumes the form of Maha Bindu. Bindu has no dimension, from which everything is born. Bindu is that Circle with Void inside. The confining Circle is Shakti, while the Void is Siva.
