There are three occult sources of our action -the superconscient, the subliminal, the subconscient, but of none of them are we in control or even aware. What we are aware of is the surface being which is only an instrumental arrangement. The source of all is the general Nature, -universal Nature individualising itself in each person; for this general Nature deposits certain habits of movement, personality, character, faculties, dispositions, tendencies in us, and that, whether formed now or before our birth, is what we usually call ourselves. A good deal of this is in habitual movement and use in our known conscious parts on the surface, a great deal more is concealed in the other unknown three which are below or behind the surface.
    But what we are on the surface is being constantly set in motion, changed, developed or repeated by the waves of the general nature coming in on us either directly or else indirectly through others, through circumstances, through various agencies or channels. Some of this flows straight into the conscious parts and acts there, but our mind ignores its source, appropriates it and regards all that as its own; apart comes secretly into the subconscient or sinks into it and waits for an opportunity of rising up into the conscious surface; a good deal goes into the subliminal and may at any time come out -or may not, may rather rest there as unused matter. Part passes through and is rejected, thrown back or thrown out or spilt into the universal sea. Our nature is a constant activity of forces supplied to us out of which (or rather out of a small amount of it) we make what we will I or can. What we make seems fixed and formed for good, but in reality it is all a play of forces, a flux, nothing fixed or stable; the appearance of stability is given by constant repetition and recurrence of the same vibrations and - formations. That is why our nature can be changed in spite of Vivekananda's saying and Horace's adage and in spite of the conservative resistance of the subconscient, but it is a difficult job because the master mode of Nature is this obstinate repetition and recurrence.
