Kundalini is the opening of certain healing channels and chakras allowing access to the Earth’s energy which is part of Universal Energy.
The Root Chakra is the bodies energy centre situated near the coccyx. The Kundalini energy gains access to the body at this point.
Kundalini energy is also known as ‘the Kundalini Fire’. From the Root Chakra the energy flows up through the body via the main energy channel and out through the Crown Chakra.
The bodies energy channel runs from the Root Chakra to the Crown Chakra situated on the top of the head. By opening the Kundalini a complete cleansing of the body and chakras is acquired over a period of time.
So where did this come from?  
Mr. Ole Grabrielsen brought Kundalini Reiki to this earthly plane. He is a Master of Meditation inspiring many throughout the world. Mr. Grabrielsen spent endless time in Holy Communion with Master Kuthumi the Chocan of the Second Ray, also known as Koot Hoomi and K.H., who is connected to the Crown Chakra and The Temple of Love, Wisdom and Understanding. Kundalini Reiki was the primary result of this communion.
At this time of change in our world, Master Kuthumi will come to those who seek world knowledge to use for the good of all. Because of our inclination towards intellectual arrogance, the Masters Energies are orientated to heal the physical body and mind.
The Masters explicit destination of Kundalini Activation to amplify states of Universal Consciousness, peace, light and love, is no longer a promise for the future, but a promise for the here and now.
There are three attunements Level 1, 2 and 3 Master. They can be achieved over a period of 14 days when you will then be able to pass on the attunements to others.  Even if you have been attuned to other systems of Reiki, but have an interest and would like to learn Kundalini Reiki, you must begin with Kundalini Reiki Level 1.  
For the attunements themselves.
When you are ready to receive them, sit or lay somewhere comfortable without any distractions. When sitting either place your arms on the arms of the chair, or on your thighs with palms facing upwards. If lying put your arms by your side with palms facing upwards. 
People’s experiences during an attunement can vary. Some people feel nothing at all, whilst others feel the energy and see things too. The feeling of energy in the hands and legs is quite normal and can intensify with the different levels. If you don’t feel anything it is nothing to worry about. As time passes, you will experience these feelings. The experience will be unique to you and what you need.
