Throughout my practice I have interacted with many people who have not been able to visualize, or have told me that they had aphantasia. From what I have found the way to get around using visualization is to simply think and will in your mind what you would like to happen. You would even be able to go through the process of speaking out loud the actions that you want to happen spiritually and mentally. You should also look into using your other spiritual senses such as clairaudience, so that you will be able to interact with the spiritual world through forms of perception that are not connected to visualization. You may also be able to build up your visualization through practice by simply exercising your visualization skills, if you are able to visualize but just not well, and do not have aphantasia.
