Within the lineage of the Trika three-fold system in Kashmiri Śaivism, there are four schools: The Krama System, The Kaula System, The Spanda system and the Pratyabhijñā system. Each system denotes different aspects of energy.
Within Kundalini, there are three different types and possibly more. These include: Para Kundalini: the supreme, Siva connection, the absolute; Chit Kundalini: Śakti energy experienced through the spine; and, finally, Prana Kundalini: the revelation of self and the lowest form of Kundalini experienced through the breath- Prana.
