Circle
What a nice philosophy is contained in the saying that everything appears as round. The reason is that when that Great Architect willed to create the universe and used the energy, the actions started in a round way in order to establish a circuit so that the energy could work. Now when this very energy got concentrated, it came to be called as solid, or matter, due to the force of the action. Now you have to remove this very solidity from the aspirant, so that he may become spirit from top to toe.
