Interesting post. My first reaction is the other nations already have a genetically modified version our our Torah. Nothing we can do about that. It should not stop us.
Secondly, I do believe Kabbalah should play a larger role in our studies.
While it is great to do things because we are told by great people what the good road is, I have learned from studying a few Kabballah influenced texts by the Ramchal, for example, that without some understanding, no matter how basic, of the spiritual ramifications of what we do here on earth, everything can grow to become a laundry list of things to do.
Kabballah “flavoring” makes doing Jewish things more dimensional, and helps to keep practice performed out of inspiration and less from being done from rote.
More Kabballah influence, please!
