Perfume is soul, soul is perfume.
In One Thousand and One Nights, there is this wonderful expression for addressing a loved one: to say “soul of my soul,” signifying the emptiness of living without one's love.
I remember Aladdin's warm voice - crackling out of a record player on a 45 rpm - speaking to Badroulboudour. He calls her "my princess, soul of my soul." I was 7 years old at the time, and I asked my mother for the meaning of soul.
She replied, "There is no single definition. It is an invisible presence that links us to the divine, a little like the Vanilla trail of the perfume that you want to follow. The soul travels to infinity in space and time and connects us to the whole. It is a fragment of that which is beautiful and perfect in each of us, that returns us to heaven and remains on earth when we disappear. Perfume continues the presence of this fragment, and the soul proceeds in the same way."
