I've pulled back from this. I'm wired one way, others are wired differently. We all, repeat we ALL, have mechanisms for spiritual experience. Every one of us. No one way is better, more thorough, or more accurate. It is how the experience and information is received and used that makes it more meaningful.
I want to briefly touch on an alternative method of spiritual experience for those who feel left out, for those who don't hear words or get flashy visuals. See, we live in a culture that emphasizes intellect and thought over emotion and intuition. It isn't what should be, we need to regain balance there.
Heart tradition is found within many indigenous cultures. It is a source of experience we all can and should look to. Rather than focusing on trying to attain an intellectual, hearing and seeing experience, why not focus on seeing with the heart? Examine the feelings, the intuition that comes from this practice. It is an experiential way of spiritual contact. The heart is holistic, it is more then just emotion but our perception of those emotions. Deep wisdom lies within and for those who have faced barriers in spiritual contact, this may be an alternative avenue.
What happens here is when one goes before spirit, rather than hearing words you feel the answer. Since many modern cultures have an ingrained distrust of feelings we often start by disregarding what is received. But stop, don't disregard, give it time to percolate. Mull those feelings over, court them gently. Over time their wisdom will be acknowledged. Over time, we'll more rapidly understand the holistic message. It can be a profoundly intimate contact, much more so than words or images.
A decent article written from an Andean paradigm by C. Michael Smith is found in the link below. If Spirit via the Heart is something that interests or may benefit you, I suggest you take a look: Andean Shamanic Vision: an archetypal psychology of the heart.
