What is "parameshashakti"

Parameshashakti in Hinduism is the power of Parameshwara or Ishvara, the conditioned Brahman. It is Maya, the anadyavidya (the beginningless avidya) that has no reality in the absolute sense but is superior to its effects and inferred by them, hence, also called, avyakta. It is established by ikshana ("seeing", "thinking"), by samkalpa ("purposing") and parinama ("transformation"). Parameshashakti gives birth to this entire world. Therefore, it is Prakrti.( Vivekachudamani.110)
