Takwin (Arabic: تكوين) was a goal of certain Muslim alchemists, notably Jabir ibn Hayyan.
Jabir states in his Book of Stones (4:12) that "The purpose is to baffle and lead into error everyone except those whom God loves and provides for!"
The Book of Stones was deliberately written in a highly esoteric code, so that only those who had been initiated into his alchemical school could understand them.
Kathleen Malone O'Connor writes: From the emic perspective of the alchemist, the act of takwin was an emulation of the divine creative and life-giving powers of Genesis and Resurrection and tapped the physical and spiritual forces in nature.
At the same time it was an act through which the alchemist was inwardly transformed and purified, a spiritual regeneration.
