evaṃ saṅkhyā samākhyātā purāṇe'sminmahātmanā |
aṣṭādaśasahasrīyā saṅkhyā ca parikīrtitā ||

Thus the Mahâtmâ Veda Vyâs has divided this Bhâgavata Purâna. into so many Skandhas and into so many chapters; and that the number of verses is eighteen thousand is already stated. That is denominated as Purâna which contains the following five characteristics:-- (1) Creation of the universe, (2) Secondary creation, (3) Dynasties (4) Manvantaras and (5) The description of Manus and other kings.
S’iva is beyond Prâkritic attributes, eternal and ever omnipresent; She is without any change, immutable, unattainable but by yoga; She is the refuge of the universe and Her nature is Turîya Chaitanya. Mahâ Lakshmi is Her Sattvikî S’akti; Sarasvati is Her Râjasik S’akti and Mahâ Kâlî is Her Tâmasik S’akti; these are all of feminine forms.
