To let the devotee enjoy them completely, the Lord manifests his krpa sakti (also called anugraha) the central pole of all energies, the supreme controlling energy, which is described in the scriptures as a queen in the middle of a lotus whose eight petals are the eight svarupa saktis (vimala, utkarsini, jnana, kriya, yoga, prahvi, satya, and isana)
I could not understand these svarupa saktis there in VCT's commentary on prema from Madhurya Kadimbini
