The Rattle has a multidemensional voice that whispers down the paths of the Otherworld.
The Rattle sets the scene defining sacred space for shamanic work.
You may wish to sound the Rattle to signal the start of Shamanic work.
You may rattle at each corner of the medicine wheel.
Shaking of the Rattle is a signal to the consciousness to switch to an altered frequency.
It is usually used as a preliminary to the Drum.
The Rattle is also used in Shamanic healing.
It diagnoses a complaint by noticing the alteration in the voice as it is passed over the body.
