Hegel famously said in his Phenomenology of Spirit, "Everything turns on grasping and expressing the True, not as Substance, but equally as Subject." (Miiler trans., ¶17). That the true - truth - is equally substance and subject.
He makes this explicitly clear in the following statement, “What seems to take place outside it, to be an activity directed against it, is its own doing, its own activity; and substance shows that it is in reality subject” (Ibid, ¶37).
Meaningful coincidences, Jung's synchronicity, are a demonstration of this truth. And the mediation of the mental and material takes place in the immediacy of the present moment. As Hegel said, "There is nothing, nothing in heaven, or in nature or in mind or anywhere else which does not equally contain both immediacy and mediation" (Science of Logic, Miller trans., pg. 68).
