druvya mana is a kind of an operating board which is connected at one end with the brain, by means of levers and bars of nerves. Its operator, too, is connected with it at the other end, and cannot break away from it during life. It is because of this inseparable association between the levers of movement and the ego that every immediate act of will is also an immediate act of the body, except when the motion is allowed to be dissipated by the brain. In the latter class of cases, the motion is communicated to certain parts of the brain where it evokes only nascent or potential movements, and is probably ultimately absorbed by the serous fuid surrounding that organ. This is why deliberations produce no bodily movement, though every true act of the will is also an immediate act of the body, as already stated.
As to the origin of motion, reflection reveals it to be the result of a purely mechanical process on the part of will. The ego is affected by its sensations, perceptions and considerations and thrown into a state of agitation in consequence. These affections or agitations of the will are communicated to the nerve terminals embedded in the dravya mana, producing characteristic movements of the body or brain cells. Where the element of selection comes in is in the choice which opens one track rather than another to the motor impulse. But this is the work of the ego, and cannot be performed by matter which is not endowed with judgment. Deliberation, similarly, cannot be a function of the brain, though it bears the full weight of the ego's activity when engaged in thinking; for no amount of the motion of that which is devoid of consciousness can ever become
