At the age of twenty, a question came to me.

"Who am I?"

Head I tried to solve it with my head, but I couldn't grasp it. Soheart I went down to my heart,

and thento the body and sexuality, the deepest well.

The energy drawn from the bottom of that wellChest and head Rising up inside,

The moment when four became one—A question lingering for 40 years has finally melted away.

Quadsapiens is not a theory made up at a desk.

It is an experience drawn from making one person's body a laboratory, and bringing it to light.
