It is that part of the human soul that is inherently governed by the law of reincarnation, propelling us irresistably down into physical embodiment, so as to ensure the evolution of our personal consciousness.

Initially, the lotus is a closed bud, but as we experience our myriad incarnations and our consciousness evolves, the petals unfold.
