The Ari writes that the דעת of Yisrael was in galus in Mitzrayim. He also writes that the דיבור of Yisrael was in Galus and that פסח is also פה סח that when the galus ended they retrieved their speech back rectified.So we have two ideas from the Ari ztl that both dibbur and daas were in galus. What is the product of both distortions? The result is not nice speech. Dinvr speech is a unique quality of man, not nice speech means you are not a nice person. In order that one’s speech should be sublime and correct, one must first use his דעת to think if he will be saying something inappropriate. His דעת must filter his speech, vetoing any negative or destructive energy.
Since the acronym of faith was such a big hit I want to leave you with another incredible one.
BEFORE YOU SPEAK THINK
T – IS IT TRUE
H – IS IT HELPFUL
I – IS IT INSENSITIVE
N – IS IT NECESSARY
K – IS IT KIND
All these questions and conditions are the usage of one’s דעת before the words blurt out of your mouth. Once they are out, you can never retrieve them or bring them back in. GONE FOREVER.
I think it is wonderful that דעת ודיבור is gematria שבת ! Incredible. The first letter of שבת is the sound of Shh! Which means be quiet. Hashem created the world with ten sayings. On Shabbos He rested from creation. That means that His dibbur ceased. So to, in emulating Hashem, we should try to minimize our talk on Shabbos. The combination of דיבור ודעת is crucial on Shabbos as its gematria bears out. If we do talk let’s make sure we think before hand in acronyms.
