Thought. Movement. Time.
Spiritual movement is not movement from place to place. Rather, it refers to a renewal of form since we denominate every renewal of form by the name “movement.”
– Baal HaSulam, The Study of the Ten Sefirot, Part 1, “Inner Reflection,” Chapter 9
The spiritual definition of time is only a sensation of movements. Our mind pictures and devises a certain number of movements, which it discriminates one by one and translates them like a certain amount of “time.” Thus, if one had been in a state of complete rest with one’s environment, he would not even be aware of the concept of time.
