The term Kundalini awakening may have different understanding. In Reiki Tummo definition, Kundalini awakening means:

1. Open Crown chakra, as the exit of Kundalini energy and pressure, and connect your self to the divine universe Reiki energy that enters your self through your crown chakra;
2. Open thoroughly the sushumna, main energy channel; from the perineum to crown chakra thus prevents pressure from building up.
3. Break the Brahma Node, the node of Base chakra, and ignite the Kundalini fire with its height at least as high as your navel chakra;
4. Connect your self to the Earth Energy that will function as Kundalini fuel in addition to the divine Reiki energy.

(*) During attunement a Reiki Master opens a student's chakras (energy centers) to enable the student to channel divine energy simply by having the intention to do so.
