The Kundalini isn't as much controlled by you as you are by it. During the early activation a person will need time to come into a balance with how the energetic re-wiring is being completed. This can be a process almost completely outside the control of the individual "ego" mind or also what I call the small ( i ).
This is an area where the most control a person can enact is that of complete surrender or allowing of the Kundalini to complete its agenda. Consciously moving it around the body isn't as much pertaining to Kundalini but to the other energetic qualities of a human body. The nervous energy, the etheric energies, the energies that exist as a result of outside attachments.
These are energies that can move as the person wills it. But make no mistake the Kundalini in action will trump or supersede all of these other frequencies of energy in the body. So if an ( i ) or ego mind wants to take control and move energy around the body Kundalini "may" respond with a severe painful response in order to teach the individual that this may not be a pleasant experience. This doesn't always occur and much depends upon the scope and quality of what the Kundalini will determine is in the interest of the person. Kundalini knows you better than you know you.
It is best to keep the idea and experience of the Kundalini as an intelligent consciousness with in a consciousness. The butterfly speaking to the larvae. - blessings – chrism
