Divisional charts from the first octave (D1 - D12) up through the second octave (D13 - D24) cover the body, heart and mind. In turn, the third octave catches much of the astral and lower causal level influences upon us (D25 - D36). Even higher-level divisional charts reach to the most rarefied domains, accessible to but a few—adepts deeply skilled in concentration and midline energy work. Nevertheless, it pays to know a few essential features from these more esoteric charts as they provide sensible hints for practice and daily living.
