meditation.. comes by a process of imagination..

Meditation , you know comes by a process of imagination.You go through all these process of purification of the elements – making one melt into the other , that into the next higher , that into mind , that into spirit , and then you are spirit
We have all these variations now and see them--- what we call the five elements—solid, liquid , gasesous, luminous , thereal.After that the state of existence is mental and beyond that spiritual.-----------Swami Vivekananda
