Once our Kundalini activates, we often become more sensitive in all meanings of the word. This can mean that we pick up the energy from those around us more easily. Because of this, it’s important to have the tools to not only protect yourself from non-beneficial energies but to also be able to clear the energies that you do still absorb.
Much of what you are clearing will be your own “stuff” - that which you are purging and releasing as the Kundalini makes its way through your system. This is a natural part of this purification process.
