Work. Good, honest work, whether it’s working with your hands to create an artwork, or manual labour, brings forth a sense of divinity at play. The only prerequisite is that whatever the work is, it is done sincerely and in congruence with the soul’s true origin and intent, then, without any effort, one experiences a flow, wherein one feels a part of the plan of the entire universe.
I've always been amused by the contention that brain work is harder than manual labor. I've never known a man to leave a desk for a muck-stick if he could avoid it.
Human labor, the manual work that people engage in to build their world, both physical and spiritual, defines the realization of their conceptual realm.
