Rabbi Shimshon Nachmani wrote his epic work "The Zera Shimshon" over 300 years ago.
He blesses the person who studies this work: “And with your eyes you will see children, and the children of your children, like olive trees around your tables, wise and knowledgeable; and houses full of everything good; both wealth and honor will not cease from your offspring”.
Rabbi Chaim Kanievski, zatza"l says learning this Sefer twice a week is a true Segula to help one receive salvation and blessing.
"Come for the Segula, stay for the Torah".
Many people become aware of life changing insights while learning.
