If you are someone who feels disgust or fear in response to insects and other small creatures, try to let it go. As you tell the story and lead the session it will be important for you not to communicate your negative associations to the children. You need to model the oneness we share with all creatures.
If you like, do a brief meditation on the session's central message. Sit comfortably. Close your eyes or find a focal point to gaze at with a soft focus. Pay attention to your breathing. As you breathe in, imagine peace and calm entering your body. Feel your oneness with the universe. As you breathe out, let go of any stress you are experiencing. With each breath, inhale oneness. As you experience calm and inner peace, repeat the refrain inside your mind: "We are all one." Continue for two or three minutes.
