Sri Aurobindo
Letters of Sri Aurobindo
Volume IV - Part 3
The opening of the physical and subconscient always takes a long time as it is a thing of habits and constant repetitions of the old movements, obscure and stiff and not plastic, yielding only little by little. The physical mind can be more easily opened and converted than the rest, but the vital physical and material physical are obstinate. The old things are always recurring there without reason and by force of habit. Much of the vital physical and most of the material are in the subconscience or dependent on it. It needs a strong and sustained action to progress there.
