Practicing the Occult, as in practicing the knowledge of the hidden?
Well, let's look at the narrative. Jesus altering reality wondrously (some would say miraculously, and some magically). Whether by walking on water, raising the dead, changing water into wine, or duplicating bread and fish, and of course healing the people.
Jesus going into the desert to confront his demons, and as he encounters Satan who offers him to rule the earth, he goes through the Dark Night of the Soul, and emerges prepared for his mission.
Jesus calmly drawing a circle in the sand, is just beautiful in my opinion considering the Biblical scene. Theoretically we can also speculate about the meaning or intention behind this action.
Jesus stressing the importance of the abilities of the True Self (you can move mountains) over dogma (the Son of Man is the Master of the Sabbath).
From the above and many other examples one can draw their own conclusion, of course within the frame of personal opinions of what constitute the occult. Is the question if Jesus dabbled with talismans, petty rituals summoning spirits, and other forms of folk magic or popular sorcery? Then I would say not according to the narrative of the gospels, where Jesus is trying to walk in the footsteps of the prophets who all had tasks concerning their people, to carry a message, to rebuke, to preform miracles, to heal. Jesus loved a good moral of the story, more than the pursuit of technical esoteric knowledge.
