"What is trust?" At the base of trust must be complete reliance on the one in whom you are putting your trust in, that he knows what is beneficial for you, as well as capable of carrying it out. Even more to really trust you must also believe that they will do everything and anything they can to help you even if they did not promise to do so.

The Zohar says "when a person immerses himself in Torah study lishmah it is as if he were standing at Mount Sinai receiving the Torah" Whenever a person reflects on Torah thoughts he attaches himself to GD's word.. Even today when learning Torah he is considered to be receiving it on Sinai
