At the heart of the Kundalini experience is something known as the initiation of Shaktipat. Shaktipat is the transfer of spiritual energy from the teacher to the student in order to initiate the kundalini Shakti. It can happen in person or at a distance. In truth we are all accessing this Shaktipat energy because our reality is made from electromagnetic fields of energy currents.
The initiation of Shaktipat is merely another symbol into the different levels of Awakening. This Spiritual energy is composed from the oscillation of given frequency waves that connect together through the collective consciousness.
Kundalini is naturally a creative energy it is the same feeling that Einstein encountered when he discovered the theory of Relativity. Likewise it the same current you feel when struck with inspiration for composing a song, painting a picture or writing a novel.
