The still more limited number of adepts who retain physical bodies remain in even closer touch with us, in order to fill certain offices, and to do c… - Charles Webster Leadbeater

In beginning this practice of meditation it is desirable to watch closely its physical effects. Methods prescribed by those who understand the matter ought never to cause headache or any other pain, yet such results do sometimes occur in particular cases. It is true that meditation strains the thought and attention a little further than its customary point in any individual, but that should be so carefully done, so free from any kind of excess, as not to cause any physical ill-effects. Sometimes a person takes it up too strenuously and for too long at a time, or when the body is not in a fit state of health, and the consequence is a certain amount of suffering. It is fatally easy to press one’s physical brain just a little too far, and when that happens it is often difficult to recover equilibrium. Sometimes a condition may be produced in a few days which it will take years to set right; so anyone who begins to feel any unpleasant effects should at once stop the practice for a while and attend to his physical health, and if possible consult someone who knows more than he does about the subject.

Most of our students are familiar with the thought of the four stages of the Path of Holiness, and are aware that a man who has passed through them and attained to the level of the Asekha has achieved the task set before humanity during this chain-period, and is consequently free from the necessity of reincarnation on this planet or on any other. Before him then open seven ways among which he must choose. Most of them take him away from this earth into wider spheres of activity, probably connected with the solar system as a whole, so that the great majority of those members of our humanity who had already reached this goal have passed entirely out of our ken.

The first difficulty that faced us was the identification of the forms seen on focusing the sight on gases. We could only proceed tentatively. Thus, a very common form in the air had a sort of dumb-bell shape (see Plate I); we examined this, comparing our rough sketches, and counted its atoms; these, divided by 18—the number of ultimate atoms in hydrogen—gave us 23.22 as atomic weight, and this offered the presumption that it was sodium. We then took various substances—common salt, etc.—in which we knew sodium was present, and found the dumb-bell form in all. In other cases, we took small fragments of metals, as iron, tin, zinc, silver, gold; in others, again, pieces of ore, mineral waters, etc., etc.... In all, 57 chemical elements were examined, out of the 78 recognized by modern chemistry. In addition to these, we found 3 chemical waifs: an unrecognized stranger between hydrogen and helium which we named occultum, for purposes of reference, and 2 varieties of one element, which we named kalon and meta-kalon, between xenon and osmium... Thus we have tabulated in all 65 chemical elements, or chemical atoms, completing three of Sir William Crookes' lemniscates, sufficient for some amount of generalization. (Chapter III.
