Self-knowledge

The first necessity for obtaining self-knowledge is to become profoundly conscious of ignorance; to feel with every fiber of the heart that one is ceaselessly self-deceived.

The second requisite is the still deeper conviction that such knowledge - such intuitive and certain knowledge - can be obtained by effort.

The third and most important is an indomitable determination to obtain and face that knowledge.

Self-knowledge of this kind is unattainable by what men usually call "self-analysis." It is not reached by reasoning or any brain process; for it is the awakening to consciousness of the Divine nature of man.

To obtain this knowledge is a greater achievement than to command the elements or to know the future.

Will and Desire

H.P. Blavatsky

Will is the exclusive possession of man on this our plane of consciousness. It divides him from the brute in whom instinctive desire only is active.

Desire, in its widest application, is the one creative force in the Universe. In this sense it is indistinguishable from Will; but we men never know desire under this form while we remain only men. Therefore Will and Desire are here considered as opposed.

Thus Will is the offspring of the Divine, the God in man; Desire the motive power of the animal life.

Most of men live in and by desire, mistaking it for will. But he who would achieve must separate will from desire, and make his will the ruler; for desire is unstable and ever changing, while will is steady and constant.

Both will and desire are absolute creators, forming the man himself and his surroundings. But will creates intelligently - desire blindly and unconsciously. The man, therefore, makes himself in the image of his desires, unless he creates himself in the likeness of the Divine, through his will, the child of the light.

His task is twofold: to awaken the will, to strengthen it by use and conquest, to make it absolute ruler within his body; and, parallel with this, to purify desire.

Knowledge and will are the tools for the accomplishment of this purification.
