by Reb Gutman Locks at Mystical Paths
The study of the mystical Torah must be grounded in the physical Torah. Not only are we are allowed to teach these subjects, but we are obligated to teach them.
Of course there are many opinions. The most well-known learned opinion, (which is an opinion, as no one knows for sure what the End Days will bring), is that there will be stages in the Redemption. In the early stages, there will still be a type of free will, which will not be in the later stages. This makes simple sense as the hope is for the ultimate revelation, and while standing there before the Revealed Presence of Hashem, who would even conceive of sin?
This means that, at some time, there will not be free will. We will be like angels basking in His glory. But, not everyone will see the same degree of this glory. It will all depend upon the work that one has done up until that time.
As for someone receiving the reward for the entire Torah by simply doing one mitzvah, we have a number of well-known stories of evil people who turned their lives around at the end of their days; and they received the entire reward. But obviously, we can not live with that hope for ourselves. For this reason, there are 613 mitzvahs and not just one. G-d, in His great kindness, has given us all of His Torah. Only a completely ignorant, or simple, person would reject even a drop of it.
Now to address what I sense in the tone of some emails and comments. It seems that some people somehow find the Torah to be an awesome responsibility, a fearful task, maybe even threatening! If this is a correct feeling, and you find yourself harboring such feelings, I strongly suggest you that find a different rabbi. Find someone who can show you the uplifting joy in every single commandment. Find someone who can show you the joy in making a blessing, and in putting on tefillin, because this is what G-d wants for us. In fact, this is why He has given us His Torah.
He has placed us in His garden, and He wants us to be happy. Your concern should be for the Jews who have not yet found that joy. And you can only help them find it if you find it for yourself, first.
Have a wonderful Chanukah, and may the light of your chanukia (menorah) fill your entire year.
