The Star Wars universe continues to grow, with plenty of books, TV shows, and other properties providing more information that the films haven’t been able to dive into as much. The Secrets of the Jedi book expands more on the balance between the Light and the Dark, possibly giving more insight to Rey and Baby Yoda’s abilities unseen elsewhere in the franchise.
As pointed out by ScreenRant, the book gives a deep study of the ways of the Force, said to be based on Luke Skywalker’s fictional notes. "Using the Force properly is all about finding balance,” the section reads. “And some Force users, particularly Force-sensitive children — known by the Jedi as Younglings — are able to tap into its energy without an obvious alignment to either side.”
“The Force simply flows through them in its purest form,” the Jedi adds. “Based on the constant struggles I've witnessed between the light and dark sides of the Force, perhaps their innate neutrality can teach us all a valuable lesson."
From the section taken, Luke seems to be suggesting that children are inherently neutral and balanced in the Force and that they become aligned with one side as they age. This essentially explains why Baby Yoda or The Child is able to perform Force Heal in The Mandalorian, with this power appearing to be more linked to balance rather than being on one particular side, be it the Light or Dark; with children being more naturally attuned to the world than that of the adults.
Star Wars: The Mandalorian Season 2 is set for release on Disney+ this October.
