You are asking about Kundalini Energy.

This is the Lords of Light.

The Kundalini Energy is very potent and should be used only in controlled situations. There are Mantras that should be repeated and can help to raise the Kundalini in a safe way, giving real insights.

Where things can go wrong is when someone is traumatized in some way, they would feel heat in the spine area and wonder what is happening, it can be frightening. If this takes place they should be given a Mantra especially to help control the Energy and help balance the Chakras.

Physically strong and grounded people will be able to control the Energy and it is a way of having a Spiritual Awakening.
