In the monthly journal ההד in the year 1932 in the month of Kislev, the Rav ztz"l talks about two basic methods of Talmud study - comparing and contrasting different sugyos and going deep into the local sugya. The Maharsha was the master of both. In addition, he lit up the world with his commentary to aggadita filled with kedusha and Yiras Shomayim.
Many tzadikim have lamented the fall of the Maharsha in the Yeshivos where his commentary is not given sufficient attention.
