44. Every day has its exterior barrier, so that not everyone would be able to enter into the goodness in it, MEANING there is darkness that veils the light, as you will find light in the first day, and also find darkness in it. AND SO, in every day there are barriers that guard like thorns THAT GUARD the vineyard, SO THAT STRANGERS WILL NOT ENTER IT. There are other types of guardians, like snakes, scorpions and poisonous serpents that protect the good, so that unworthy people will be unable to enter. If there were no barriers, all the wicked would have the ability to access the secrets of the Torah.
