BY gosh, doesnt any one believe these days that anything is possible.
Of cause you can turn into a dragon, but it would take a seveir amount of your time and energy to do so.
the only reason why most people cant shapshift is that they r too lazy to put that much energy into it.
Im not saying im not lazy, ive never shapeshifted, and im not going to spend years of training to
BUt i think the point of saying you cant is so that you dont get into a stage where after one week of performing sum raNDOM spell you found on the internet of how to turn into a dragon or watever, will get your hopes down and you may stray from the path of enlightenment.
The dragons are mythical creatures who they are in the Astral World(another Astral plane). Those creatures used to hold a lot of knowledge. The only way to speak with them is to use meditation and Astral Projection. Now, about transform yourself into one of them is almost impossible on that plane. It requires a lot of energy and belief, more than a human could ever produce. If someone could ever do that, that could be a miracle.
