To picture the structure, dynamics and formative forces making up the perceptible physical universe we can begin with gross Matter and work upwards from that low frequency domain or subdivision to the higher one of Mind or the compound interetheric, using general terms which can be refined as we go along. We will see there is no hard or solid matter - there is only energy in various degrees and types of motion. See Figure 1.3 - Subdivisions of Matter and Energy. (Many words are defined or referenced to definitions and useage in the Compendium and Definitions). However what vibration is is somewhat different than conventionally thought and this is discussed in some detail in Part 08 - What Vibration Is. - Part 1 and Part 09 - What Vibration Is. - Part 2.
