The concluding knowledge of this chapter would be that the "cocoons" consist of two unequal parts, which Juan Matus [11,14,16] called
"bubbles of perception". This name originated from their similarity with swimming-bladders of some types of fish.
The division of the "cocoon" into the two "bubbles of perception" takes place at the collar-bone level. The upper
"bubble" includes the head and the neck, while the lower one encloses the rest of the body. In other words the upper
"bubble" includes the upper dantyan, and the lower — the other two and the legs.
The upper "bubble" is very important for communicating with material world, while we use the lower
"bubble" for communicating with the non-material one. A practitioner can perceive from them separately either material world or other eons.
The quantitative growth of consciousness and meditative work are performed primarily by the lower
"bubble of perception".
The main part of it is the middle dantyan, refining in and expanding from which we get closer to Perfection. It is not the first time I emphasize this, because this is the most fundamental basis of the entire psycho-energetic work, and any deviations from this mainstream lead to prolonged straggling and to wasting of so valuable time of being in these bodies on Earth.
Harmonious development of the second important component of the lower "bubble of perception" — hara — is also absolutely necessary for meditative achievements. But regarding this structure as the basis for spiritual growth, which is typical for many martial arts schools, is a gross mistake.
The overall energy structure of the body can also be considered as consisting of 4 vertical segments. But talking about it in practical terms makes sense only at significantly more advanced stages of spiritual development.
