The verse states, ‘If you seek it like silver and search it like a treasure, then you will understand fear of Hashem, and will find knowledge of G-d’. One thing we learn from this is that one should invest efforts in learning like he does in acquiring money. A person is willing to leave the comfort of his home and suffer hardship travelling, especially if he sees he cannot make it in his hometown, and especially if he knows that in a certain place he can become rich in a short time. Similarly, a person sees that he cannot learn properly at home, he should go somewhere where he can learn quietly, and the gain from this is immense, for he can collect spiritual riches in a short time that he could never gain at home.
ח׳ בסיון ה׳תשפ״א
"והאמת בלתי שום ספק כלל, שאם היה העולם כולו מקצה עד קצהו פנוי חס ושלום אף רגע אחד ממש מהעסק והתבוננות שלנו בתורה, כרגע היו נחרבים כל העולמות, עליונים ותחתונים, והיו לאפס ותוהו חס ושלום". (נפש החיים) 1
