Zukav distinguishes the "Old Male" (five-sensory, protector, provider) and the "Old Female" (five-sensory, child bearer, homemaker) who join in marriage in order to enhance probabilities of survival and comfort from the emerging "New Male" (multi sensory, intuitive, emotionally aware) and the "New Female" (multi sensory, capable in all chosen endeavors) who join in a new kind of relationship in order to create authentic power and assist each other in creating authentic power. He calls this relationship "spiritual partnership" and defines it as "partnership between equals for the purpose of spiritual growth". According to Zukav, "spiritual growth now requires relationships of substance and depth" and only spiritual partnerships are able to support all multi sensory individuals (not only couples) in creating authentic power. Zukav posits the "Universal Human" as the ultimate potential of the emerging multi sensory humanity – a human who is "beyond nation, religion, race, sex, and economic status; a Citizen of the Universe whose allegiance is to Life first and all else second".
