I'm not certain if I'll ever overcome a personal "weakness"...considered to me more likened to a phobia, I'd say...that would be the fear of being submerged underwater. I've confronted this weakness/phobia every time I was invited to go swimming in a pool. I'm ok so long as I can feel the bottom of the pool with my feet. People have attempted to teach me how to swim, but I just seem to panic whenever I may try to swim on the surface of a pool with arms and legs extended.
I personally believe that my weakness/phobia is not connected with any traumatic experience associated with water because there were never any traumatic incidents that occurred during all the previous years of my life. Which leads me to surmise that the trauma may have its source from a pastlife.
My theory on this and many other phobias that people are afflicted with, once childhood experiences are ruled-out of course, is that my fear of being submerged underwater originates from the manner by which I passed-away in a most recent pastlife.
Another example of a phobia that may have links to a pastlife is the fear of heights....or the inability to withstand being on a large ferris wheel; on an aircraft or standing at the edge of a cliff. This phobia may have been caused by falling from a high place which ended that pastlife.
These of course are theories because there may yet be discovered, a very specified genetic code that fires for certain people, that may be causing various phobias or even ailments to suddenly appear on the surface of our bodies. Then again, the genetic codes may be a reflection of a soul's past incarnations as well. It could actually go both ways.
However, my serious contention on that is that we're all spiritual beings having human experiences and that our physical make-up or genetic background does not encapsulate whom each of us truly are.
This is why I've been on a personal spiritual quest to solve these type of mysteries of the human condition, and why I've always been fascinated by human behavior, which has become the precipitous to pursue a profession in psychology.
This is now heading rather outside the realm of the original question about overcoming mental or physical weaknesses, so it would be a good idea not to go any further with other commentary that I would like to share with everyone in the Blurtit realm...and for this...please accept my apology for ranting on this way, Nascarnut.
I've a homepage/website www.angelfire.com/tx3/YantraOm
that addresses the innerworkings in the deeper recesses of the mind. Levels of consciousness/awareness that far exceed the limitations of 5-sensory input/output physical reality. All are welcome to visit any time. The best way I'm ever going to tackle my weakness/phobia is most likely by facing it head on without reservation or hesitation. I'll have to try that some time soon...perhaps after this fall and winter....aww shucks...is summer already over??
