These adjectives mean beyond human power to explain or understand. Something mysterious arouses wonder and inquisitiveness: "The sea lies all about us.... In its mysterious past it encompasses all the dim origins of life" (Rachel Carson).
What is esoteric is mysterious because only a select group knows and understands it: a compilation of esoteric philosophical essays.
Arcane applies to what is hidden from general knowledge: arcane economic theories.
Occult suggests knowledge reputedly gained only by secret, magical, or supernatural means: an occult rite.
Something that is inscrutable cannot be fathomed by means of investigation or scrutiny: "It is not for me to attempt to fathom the inscrutable workings of Providence" (Earl of Birkenhead).
