In Spirital - A Real Soul Evolution Experience, Lark Lauren undergoes a transformation and starts paying attention to the spiritual world, to what is all around us, and to what we take for granted. In Spirital - Making Sense, Lark Lauren makes sense of his experience and associates it with existing and newly created concepts.

Spirital – Making Sense, the second volume of the Spirital series, is a brainstorming where Lark Lauren is making sense of his experience and associates it with existing and newly created concepts. 

Spirital - The Symphony of Coming Home, the third volume of the Spirital series, follows the transformation Lark is continuing to experience from the physical and the spiritual perspective. It culminates with the awakening of the kundalini force.

The books discuss concepts like awakening, friends, money, business, goals, spirit, books, music, poetry, movies, trends, parallel universes, time and many more⁶. They put these concepts and experiences in perspective and in relation to modern society, science and contemporary challenges.
