Answer: Spiritual sensations are not transmitted, but pass to the next incarnation as Reshimot (remembrances) of information, and the person continues his spiritual development from the previous level.
Suppose that I was born in the 20th century and toward the age of 40 I attained a particular spiritual level. In the next incarnation, I will attain my spiritual level toward the age of 30 thanks to having already learned the wisdom of Kabbalah. This level will be much higher because by that time there will be a general acceleration of the world.
