qualities of reality and their realisation in the four dimensions of space. When emphasising this monism, Rodnovers may define themselves as rodnianin, "believers in God" (or "in nativity", "in genuinity"). Already the pioneering Ukrainian leader Shaian argued that God manifests as a variety of different deities. This theological explanation is called "manifestationism" by some contemporary Rodnovers and implies the idea of a spirit–matter continuum; the different gods, who proceed from the supreme God, generate differing categories of things not as their external creations (as objects), but embodying themselves as these entities. In their view, beings are the progeny of gods; even phenomena such as the thunder are conceived in this way as embodiments of these gods (in this case, Perun). In the wake of this theology, it is common among Slavic Native Faith practitioners to say that "we are not God's slaves, but God's sons", many of them emphasising the ontological freedom of the different subsequent emanations so that the world is viewed as a "dialectical manifestation" of the single transcendental beginning and continuous co-creation of the diversified gods and the entities which they generate. The Russian volkhv Velimir (Nikolay Speransky), emphasises a dualistic eternal struggle between white gods and black gods, elder forces of creation and younger forces of destruction; the former collectively represented by Belobog and the latter by Chernobog, also symbolising the spiritual and the material. Such dualism does not represent absolute good and evil, but the black gods become evil when acting out of agreement with older and stronger white gods. Pantheons of deities are not unified among practitioners of Slavic Native Faith. Different Rodnover groups often have a preference for a particular deity over others. Some Rodnover groups espouse the idea that specific Slavic populations are the offspring of different gods; for instance, groups relying upon the tenth-century manuscript The Lay of Igor's Host may affirm the idea that Russians are the grandchildren of Dazhbog (the "Giving God", "Day God"). The Union of Slavic Native Faith Communities founded and led by Vadim Kazakov recognises a pantheon of over thirty deities emanated by the supreme Rod; these include attested deities from Slavic pre-Christian and folk traditions, Slavicised Hindu deities (such as Vyshen, i.e. Vishnu, and Intra, i.e. Indra), Iranian deities (such as Simargl and Khors), deities from the Book of Veles (such as Pchelich) and figures from Slavic folk tales such as the wizard Koschei.
