You were given a physical body for this life, which in its variety, complexity and functionality is an excellent tool. But the physical body is more than a tool, because it became part of your existence. Although this aspect of your being is only temporary, for the time of this incarnation it is an important part of you.
For each incarnation you only receive one physical body, varying in detail, depending on the tasks you scheduled, programmed for certain abilities (like they say, “it’s in the genes”). Regardless of the tasks it is important for everyone to maintain the physical body and keep it in good condition. As your soul is connected with the physical body, disharmonies and blockages within the soul have an effect on the physical body as described in chapter 9, but this effect is not a one way street. When a human being mistreats or neglects the physical body, this can have an effect on the soul. This occurs especially when a human purposely damages the body or has someone damage it (e.g. masochists). Such a behavior leads to deeper psychological problems affecting the soul, even though the original cause may have been psychological but can also have been caused from mental planes (e.g. curiosity). Here you can see the connection between all parts and aspects of the human being. However, in this case an action on the physical plane has an effect on the physical body which loops the effect to the soul plane, causing growing confusion and destruction of values and morale, engaging in a feedback loop involving this human more and more until possible total destruction of the physical body. This is only an example regarding masochism, but I need to point out that this effect begins when less dramatic actions are taken that have self destructive or at least self damaging consequences. Among such are the use of drugs, but even so-called “harmless” drugs like caffeine, nicotine and alcohol. These have destructive powers which will also affect the soul level and disturb the harmony of your soul. Other causes of effects for your soul through the physical body are unintentional, negligent destruction of body parts or their over exhaustion. The latter does not mean that the physical body should be not used physically or that strain should be avoided, because the physical body can only remain healthy when exposed to regular, but moderate physical exercise. From what I said it should be clear that it is of great importance to keep the physical body as much as possible in a good condition, as damages and negligence can have an effect on your soul.
