The underlying theme of Elixir is a teaching that stands at the heart of Mulla Sadra's writings and those of many other Muslim thinkers: the importance of self-knowledge in each person;s journey of "Origin and Return."
Each soul originates with GOD, and one's journey is completed only when the soul has returned to Him.
Self-knowledge is the means by which the soul, having been created in the divine image, must realize its full and final potential; and philosophy, in Sadra's view is the most direct path to that end.
Sadra sees the soul's climb to perfection as a gradual disengagement from all embodiment and materiality and a return to her transcendent essence.
The returning soul comes to see that all realities and essences are found in the Intellect from which all things have descended, and that their corporeal appearance is a temporary affair.
In Sadra's way of looking at things, everything in existence is traveling on a path that ends up at its rightful place with God.
The movement of all creation on the path of Origin and Return, or from First to Last, is a great manifestation of God's wisdom and compassion, culminating in a state of permanent happiness for all creatures.
