The "Devi Sukta" ideas of the Rigveda are further developed in the relatively later composed Shakta Upanishads, states McDaniel, where the Devi asserts that she is Brahman, from her arise Prakṛti (matter) and Purusha (consciousness), she is bliss and non-bliss, the Vedas and what is different from it, the born and the unborn, and the feminine is thus all of the universe. She is presented as all the five elements, as well as all that is different from these elements, what is above, what is below, what is around, and thus the universe in its entirety. This philosophy is also found in the "Tripuratapani Upanishad" and the "Bahvricha Upanishad".
