Transmigration was the skill of defying the laws of physics and pulling objects out of thin air.

The Hermit taught it to the Doctor; when the First Doctor revisited the hermit toward the end of his life, the Hermit transmigrated a bone-china tea set and the Doctor transmigrated a jug of yak's butter, though it was ugly due to rhematism stiffening the Doctor's wrist. The hermit noted that the Doctor always did better at transmigration while his hands were in his pockets. (PROSE: The Three Paths)
