Cravings and Desires

These cravings and desires are old habits of the physical which came to it from the universal Nature and which it accepted and took as part of itself and its life. When these things are rejected by the waking consciousness they try to take refuge in the subconscient or else in what may be called the environmental consciousness and from there they press upon the consciousness trying to recover their hold or simply to recur for a time. If they are in the subconscient they come up most usually in dreams, but they may also surge up into the waking consciousness. If they come from the environment they take the form of thought-suggestions or impulses or a vague restless or disturbing pressure. It is probably this environmental pressure that you feel. When the body is full of the new consciousness, Peace and Power at the same time, then this outward pressure is felt but can no longer disturb and finally it recedes to a distance (no longer pressing immediately on the physical mind or body) and either gradually or rapidly disappears.

By environmental consciousness I mean something that each man carries around him, outside his body, even when he is not aware of it,—by which he is in touch with others and with the universal forces. It is through this that the thoughts, feelings etc. of others pass to enter into one—it is through this also that waves of the universal force—desire, sex, etc. come in and take possession of the mind, vital or body.
