According to the cognitive theory of metaphor, conceptual metaphors are an integral part of the human mind so that we can see these metaphors in all aspects of human thoughts and actions. A part of these metaphors is shaped based on up/down spatial orientations. Based on these metaphors, spatial orientations play a significant role in human understanding of many abstract concepts. These orientational metaphors are visible in ordinary and natural languages, as well as in specialized and scientific texts. It is shown in this paper that a part of these up-down orientational metaphors have also been used in Mullā Ṣadrā\\\\\\\\\\\\\\\'s philosophy: the “Having Control or Force Is Up, Being Subject to Control or Force Is Down ” metaphor has been used to understand the causal relationship. The “Good Is Up and Bad Is Down” metaphor makes understandable that the source of good attributes is in transcendent and higher world and the source of bad attributes is in material and lowest world. The “More Perfect Is Up and Less Perfect Is Down” metaphor has been used to understand the gradational hierarchy of the beings.
