Earth and Sky Meditation

Sit quietly, close your eyes, and let your thoughts go. Breathe deeply, and concentrate only on your breath. Be still, and let your mind be still. Embrace the silence. Now, in the silence, feel roots growing from your feet. Feel them push and dig through the earth, reaching downward through the soil and the stone, spreading deeper and wider until they reach the waters under the earth; that dark, cool, silent power that is the Mother of life.
Draw this power upward, up through your roots and into your feet, rising with your breath, up through your legs, into your loins, gathering there in a cauldron of earth power. Let it rise upward through your breath, up through your spine, up to your heart where it swirls and gathers into a restoring cauldron of earth power. Breathe, and draw the power up into your head, behind your eyes, filling a cauldron of wisdom that fills you with silvery light. Let this power fill your body, flow out from the top of your head, flow from your fingertips, spill out of your every cell to soak back into the earth. You are filled with the power of the earth, the power of the source of life.
Now cast your gaze skyward, to the moon and sun and the far-off stars. Focus on the single bright star directly over your head. Draw its shining power down, pulling gold from the sun and blue-white from the moon. Draw the power down into your head, where it mingles with the silvery earth power and ignites the cauldron of wisdom behind your eyes. Let the power flow down into your heart and ignite the cauldron of love and healing there. Let it flow down into your loins and ignite the cauldron of creation and regeneration there.
Feel the powers of earth and sky, mingling and swirling inside you. Feel the three cauldrons, full and blazing with golden and silver light, pulsing inside you. You are full of the humming, vibrating power of earth and sky. You are the Tree, roots in the earth, branches in the sky, the nexus of all worlds.
The powers are balanced in you, source of all magic and creation. You may relax, breathe, and let them flow back into the multiverse before you open your eyes, calm and refreshed. Or you may travel further and use these powers to voyage onward, to shape your world.

Thanks to many, many Druids - this is just my own version of the tool.
