the approach

"Rav Yisroel Salanter said there is no general rule of how to serve G-d properly and this rule is also not an absolute rule. This is because the majority of distinctions and differences are a function of the place and time and thus it cannot be said one approach is "the approach." Rav Binyomin Silber, Otzar Gedolei Yisrael

interesting

"A person only learns Torah if he finds it interesting." Talmud Avodah Zara, 19a

Rashi: "A student should only be taught the Gemara that he is interested in."

these things which seem strange

"When a person beings to learn in yeshiva for the first time, it is important that he have a teacher who will properly explain what he needs to know. The teacher should also be available to explain to him these things which seem strange." Rav Moshe Feinstein, Igros Moshe, YD 4:38-7
