In terms of why I found spiritual practices to be actually not really supporting in comparison to simple practical common sense is the following.
What are the facts: we react to specific words, images, pictures, experiences, feelings, emotions, memories. Regardless of how much we would like to doubt, we are existing on a word-based system. It sounds so liberating to have some magical energetic experiences, based on mantra, for instance OM, because it resonates the galaxy or whatever and thinking that it is a specific and special word if we speak and sound and contain and express, then it would help us. I’ve experimented with this and what I’ve found was fascinating.
