Understanding the human soul has become a popular subject among Muslim and Western philosophers. In Western thought, it is interpreted that the soul and spirit are one and the same entity. There is no distinction between the two. However, this differs from the perspective of Muslim philosophers, as explained by Ibn Arabi, who posited that the soul and spirit are distinct, with the spirit being the source of human life inseparable from the body. This paper aims to fortify the spirit. The research employs a descriptive and analytical methodology from Ibn Arabi's viewpoint. Using this method, we can draw several conclusions: Firstly, Ibn Arabi's understanding of the soul is that it is the essence of a human being, inseparable from the soul. Secondly, there are three elements to strengthen the spirit: self-reflection (muhasabah), purification of the self (tazkiyyatun nafs), and striving (mujahadah). Thirdly, after undergoing this strengthening process, it culminates in a state of happiness brought about by the fortification of the spirit.
