Torah 133: Rabeinu teaches us that sometimes something so small can block our vision from seeing something so great, even when that awesome thing is standing right in front of us. The same is true of the Torah and the Tzadikim: their light is constantly shining but the vanities of this world (which in comparison to the Torah is thousands and myriads smaller than the light of holiness) is blocking out our eyes from seeing this great light!

Torah 134: Rabeinu teaches us that teaching Torah in public or to a single person can be very dangerous. This is because sharing something which isn’t fitting for the listener to hear can result in committing sexual immorality, G-d forbid.
