The universe evolves from the unknown, into which no man or mind, however high, can inquire, on seven planes or in seven ways or methods in all world… - William Quan Judge

How man has come to be the complex being that he is and why, are questions that neither Science nor Religion makes conclusive answer to. This immortal thinker having such vast powers and possibilities, all his because of his intimate connection with every secret part of Nature from which he has been built up, stands at the top of an immense and silent evolution. He asks why Nature exists, what the drama of life has for its aim, how that aim may be attained....

2. Concentration, or Yoga, is the hindering of the modifications of the thinking principle.
In other words, the want of concentration of thought is due to the fact that the mind — here called "the thinking principle" — is subject to constant modifications by reason of its being diffused over a multiplicity of subjects. So "concentration" is equivalent to the correction of a tendency to diffuseness, and to the obtaining of what the Hindus call "one-pointedness," or the power to apply the mind, at any moment, to the consideration of a single point of thought, to the exclusion of all else... Upon this Aphorism the method of the system hinges. The reason for the absence of concentration at any time is, that the mind is modified by every subject and object that comes before it; it is, as it were, transformed into that subject or object. The mind, therefore, is not the supreme or highest power; it is only a function, an instrument with which the soul works... (Book I, Concentration)

It is not a belief or dogma formulated or invented by man, but is a knowledge of the laws which govern the evolution of the physical, astral, psychical, and intellectual constituents of nature and of man. The religion of the day is but a series of dogmas man-made and with no scientific foundation for promulgated ethics; while our science as yet ignores the unseen, and failing to admit the existence of a complete set of inner faculties of perception in man, it is cut off from the immense and real field of experience which lies within the visible and tangible worlds. But Theosophy knows that the whole is constituted of the visible and the invisible, and perceiving outer things and objects to be but transitory it grasps the facts of nature, both without and within. It is therefore complete in itself and sees no unsolvable mystery anywhere; it throws the word coincidence out of its vocabulary and hails the reign of law in everything and every circumstance.
