Travel meditation allows you to send part of your consciousness to far away places and to do amazing things. The Tree of Life is one of these places, filled with mystery, wonder, and learning.
In group meditations, traveling to these nonphysical places is even easier, as you have the group energy to pull on to help you. When we do our group meditations this is often what I see in the HAS meditation room. Everyone participating in the meditation has a counterpart of themselves here. From this point you can launch yourself to higher reality planes, like other Tree of Life or the Aethyrs, for learning and spiritual growth.
