When, however, the effect of the rotation of the atom is so strong that it begins to affect other atoms outside its individual ring-pass-not, another influence begins to make itself felt, which draws together, or dissipates, those contacting coalescing atoms. Thus forms are built under the impulse of aggregated forces of some one kind, and these forms in turn produce effects on other cohering atomic forms, until the rhythm is built up, and a [1040] vibration instigated which is a continuation of the rotary motion of the individual atoms, and the modification produced on them by their group activity. This causes progression and simultaneous rotation. The movement forward is modified considerably by the internal atomic activity, and this it is which causes that motion we call spiral cyclic. It demonstrates in all forms as a tendency to repeat, owing to the backward pull of the rotating atoms, and yet is offset by the strong progressive impulse of the form activity. Students can work this out in connection with:

• The planetary Logos, as He manifests through the rounds, each one of which, in its earlier stages, recapitulates all that has preciously occurred.
• Man, in the antenatal period, in which he runs through the various stages of development.
• Spiritual man, as he creates that which will destroy the "Dweller on the Threshold.

This spiral-cyclic activity, which is distinctive of all forms, can perhaps be comprehended more practically if we study it as an expression of four laws, taking each one briefly in turn:
