The more intense the meditation and visualization, the more helpful these posters can be. For instance, the Taoist Bubble Visualization and Meditation is pretty complex. You don't only visualize a bubble of energy around your body, but also the flow of impurities out of the body, the absorption of healing energies into the body, and the blocking of negative energies from entering. This complexity is why I often have the energy bubble as the last part of a longer meditation routine.

A great way to make things simpler, and easier to remember, are these posters! There is a lot to visualize while you meditate in this form, so a poster on the wall or the floor that reminds you of the steps and the parts of the visualization can certainly be a big help.

This poster has more text, and reminds you of everything you need to know about the visualization. The other poster has fewer words, and may help you concentrate once you have the meditation memorized.

Good luck, and Happy Stretching!
