Interesting... Perhaps, you, me and others who cannot take a few deep breaths, focus and visualise, require going to a deep meditative state before reaching our gateway to visualisation?
A long time ago, I did a group mediation and had a wonderful visualisation that gave me so much peace. I often recall the memory of this. The visions I see when tired are more entertaining, so it would be wonderful to be able to have them on call.
I intend, for the both of us, the ability to reach the gateway to visualisation with ease.
