The First House is commonly referred to as the House of Self. The cusp of the First House is the home of the Ascendant, the sign that was rising on the eastern horizon at the precise moment of one's birth. By thinking of this in terms of sunrise and new beginnings, one begins to grasp the concepts of the First House. The new beginnings here are centered on the individual: the self and the attendant voyage of discovery that define a person. Who are you? What will you become? How do you realize your best self? The First House speaks to the realization of one's ultimate potential. This process of becoming a unique individual is one of the greatest contributions we make to the world in which we live.
The distinct qualities that we possess are often referred to as ‘personality’. The First House addresses the individual and their comportment and approach to life. In other words, the sum total of one's being. This is the package we give to the world. The packaging itself, or our outer being, is also governed by the First House -- the physical body and the way in which we present ourselves and, in particular, the head and face.
The First House also rules early childhood. Everything from our earliest steps to our view of the emerging world is considered here. How will we develop? What is our view on life? It all begins at the beginning (the First House) and serves to shape us for all time.
In sum, the First House speaks to the person we are becoming and will become, both internally and externally. It addresses our personality and presentation to the world, our essential qualities, approach to life, demeanor and basic sensibilities. The inner self and outer body are what the First House is all about.
