Then you should mentally analyse the problem you want to solve and, asking for the help of the tree, interact. Remember it is vital that you feel a flow of energy from the tree!
Although sensations vary, the necessary state is comparable with a very slight vibration inside you. That is the indication that interaction is taking place. Feelings are the best guide to the length of a session.
We should like to stress that you can work with trees both holding the cylinders and without them. A tree is in itself a powerful source of energy. It is therefore possible to interact with the energy of trees without the cylinders and obtain a substantial healing effect. However, the "Wands of Horus" can greatly enhance the ability of the body to perceive and transform the energy flow from the tree, reducing the time for the body to get tuned to the perception of the energy flow.
Not only the Druids, but also the ancient Egyptians knew of, and judging by surviving monuments, used the healing energy of trees.
The most obvious way of passing on such knowledge so that it could be understood by people centuries later without the need for any language was a drawing. Using the language of symbols, the Ancient Egyptian priests left us information that the sycamore tree possesses energy important to human beings.
