Different Conceptions of Development Signified by Movements along the Bronchial Tree

The movement from the proximal to the distal portions (relative to the root) of the bronchial tree may be interpreted as the general evolution and development of the entire universe; from the first evolute (mahat) of nature signified by the primary bronchus, containing within it all possibilities and forms in latent form; and the gradual march from it towards diversification and the multiplicity of particular substances.
On the microcosmic level, this would represent the development of the body from the initially undifferentiated state of an embryo. The cells in the embryo seem to divide in the same pattern as the bronchial conduit. The progression is the same; 2, 4, 8, 16, 32, etc.
The movement in the opposite direction i.e. from the level of the alveoli and the respiratory bronchioles, may also be interpreted as a movement of creation--pertaining to the development of a particular product, the brain for instance. It shows how through the integration of simpler products and ultimately parts and particles, a particular product is built.
In the specific context of the bronchial tree, the unfurling of the world-lotus which is looked upon as the movement of creation, may, when considered in conjunction with the accompanying vasculature, also represent the gradual "burning up" and destruction of the world. Seen in this light, every creation, in a sense, is also a process of destruction. And the conventional movement of involution and winding up of the world may in a certain light be also the movement of creation;  when the integration of the bronchial conduits is considered along with the "clumping" and "coagulation" of the p. vein.
