Relativity – Relativity Associated with Einsteinian physics; the first postulate of the theory of relativity is the relativity of all motion, a return to the idea of Newton, which holds that there is no stationary ether or any fixed system of coordinates in space, with regard to which motion can be measured.
The second postulate states that the velocity of light in free space appears the same to all observers regardless of the relative motion of the source of light and of the observer. A well-known feature of the theory is that by which space and time are no longer treated as independent, but as component elements of a four-dimensional continuum, space-time, and in which the objects whose position and motion are measured are called events. This is a movement in the direction of simplification, since it economizes the number of separate data which we must assume in order to build up our system of interpretation. Einstein also postulates the relativity of the force concept, thus obviating the objection that the Ptolemaic system is dynamically inadequate as compared with the Copernican.

Apart from this scientific use of relativity, its wider meaning is of prime importance in theosophy. Though we may say, in a general way, that all things are relative to each other, yet for purposes of reasoning or calculation it is necessary to assume certain things as constant; as for instance, in measuring velocities on the earth, we may assume that the earth is motionless; though when we enter the field of astronomy, we regard the earth as in motion with regard to the sun, and again may regard the sun as in motion relatively to some other position assumed as at rest. By applying this principle we arrive at the conclusion that nothing in the universe, whether physical, astral, mental, or spiritual, is completely specified to our human mind except by its relations to other things. This principle is expressed by such sayings as that all objects are manifestations of a universal principle or that there are no absolutes.
Thus the word immortality, for example, does not refer to a particular state of existence for the liberated soul, for the various elements of our complex nature have varying degrees of immortality. Each has its own cycle of existence, longer or shorter; and “absolute immortality” can apply only to the ultimate essence of man. In the same way good and bad are regarded as relative terms. This does not mean, however, that good and bad differ from each other solely in being relative to each other…..
