Rabbi Yaakov Smit is addressed in correspondence from the Lubavitcher Rebbe as a rabbi and communal leader involved in organizing and guiding Jewish educational activities, particularly the study of Chassidus and practical halachah within his community.
In a letter dated 18 Teves, 5715 (1955), the Lubavitcher Rebbe expresses his pleasure upon hearing from Rabbi Smit about a monthly gathering in his area, which has led to an increase in the study of Chassidus. The Rebbe emphasizes the importance of also studying the laws necessary for daily Jewish life (halachah), whether in a group or individually, ensuring that all participants become proficient in these essential laws. Drawing from experience, the Rebbe advises that it is best to first focus on mastering the practical laws themselves, without delving into their sources. Only after achieving proficiency should the sources be introduced in subsequent study sessions. The Rebbe underscores that the primary goal is to "Fear G-d and keep His commandments, for this is the whole person," highlighting the centrality of practical observance in Jewish life.
