I would say this is my strict definition: I would add that a looser definition of spiritual (and I think this is effectively what Sheldrake is saying) is anything that gets you out of your analytical mind and into the empathic/intuitive mind such as reading poetry or painting flowers, because using the empathic/intuitive mind could be difficult for someone who is not used to it and reading poetry might be an easier way to get started than diving in to classes in mediumship as their first step. If I had to describe spiritual in two words I would say "connectedness" and "love". If I had to use one word I would say "empathy" because that connotates (at least to me) both connectedness and love. I describe the spiritual mindset as empathic/intuitive because intuitive implies connectedness (at least to me it does). I think somewhere else I wrote that studying evidence for psi and the afterlife can be spiritual if it puts you in a spiritual mindset. That is true of a lot of things. You can approach them with the analytical mind or the spiritual mind. Sheldrake described it as feeling uplifed and inspired. I would describe it as feeling connectedness and goodwill. Spirituality is a feeling. When you use the analytical mind, you eventaully become fatigued. When you use the spiritual mind it is restful.
