"In Hindu metaphysics the polarity of being, represented by Siva and Sakti, on a higher level becomes sheer unity and blends in the androgyne Ardhanarisvara. In the Satapatha Brahmana gods and demons engage in a contest. The god Indra says 'One' in the masculine form (eka), and the demons answer 'One' in the feminine (eka). Indra says 'Two', masculine dual (dvau), and they answer in the feminine dual (dve). When five comes up (panca), the devils are silenced. Five is above gender; it contains both odd and even (3 + 2), divisiveness and contrast; with five the four quarters centre (4 + 1) on the heart. Five symbolizes the androgyne as an achievement, as a return from polarity to unity ." E. Zolla, The Androgyne, p.5.
