How do you grow your soul and spirit together?

Let truth and love reign in your heart and universal benevolence guide your actions to your fellow creatures. 

If such principles obtain among you, if this brotherhood of feeling and acting be established, your soul and spirit will grow together in beautiful proportions, and the change called death will be looked upon as merely an opening to a better life, instead of being regarded, as it now is, as a thing of dread and horror, of which you dare not think and on which you are afraid to look.

―Spirit L. D.
