Find a position which suits you best regardless of whether you are sitting or lying down and relax. You can close your eyes, but you don’t have to.
And listen.
Receive and take note of every sound that reaches you. And when you are ready, sing. Let the sounds and melody just come to you. The orchestra in the forest will accompany you, and soon you will be in perfect harmony. By doing that you will raise the energy levels of everything around you, and you will have a melody which will always take you back to the day that you sang with the forest.
