Development begins as a physical activity. The energy released by the physical is always the lowest and the conscious awareness of the being is also at the lowest in the physical and highest in the mind. The true centre of energy is vital. It is the vital that energizes the body as well as the mind. Still, the physical work releases the energy in low volumes. Mind, by lending its comprehension to the vital, is capable of energising it several-fold. As the development experience started with the physical and essentially remains in that plane, development is necessarily slow and unconscious.
