Being between genders- neither male or female, or maybe being both, was thought to be a gift in the past, and still is considered sacred in some societies today.
In many "shamanic" traditions, there was the idea that combining the characteristics of both sexes and both genders could connect one to a transcendent spiritual realm. Two-spirited folks were messengers of the Creator, visionaries, dream interpreters, keepers and teachers of spiritual principles, and medicine people. They were called on to do burials, bless unions and births and perform other ceremonies. Because they embodied both Mother Earth and Father Sky and held both a masculine and feminine heart within their souls (two spirits), they were perceived as having twice the power.
They were thought to be more able to be fair and to be able to see into the hearts of males and females. Since they inhabited both masculine and feminine in one body they were thought to be able to “see” with both the eyes of men and women. This made them mediators and bridges. They were also seen as mediators between two worlds- that of Spirit and the human world, as well as between partners, tribe, and nations. In older world religions, the gods and goddesses in-between genders were viewed as whole-gendered and therefore balanced.
