How to get into spiritual life?

The pathway to spirit life leads one to the sphere he is adapted to occupy. 

The outer covering of the soul of the indwelling conscious self is composed exactly of such material as the sphere to which it gravitates. While on earth our physical organisation is evolved from the various elements, and connected with it is the indwelling spirit. Acts of licentiousness, intense selfishness and a life in the purlieus of vice modify the character and texture of the latter and prepare it for a sphere corresponding with the life led on earth.
