Unlike what others think, that the main goal of a yeshivah is to prepare rabbonim, shochtim, and other klei kodesh [teachers, mentors, etc.], the main and top priority is to prepare Yidden who, before they venture out into the world to become baalei batim (businessmen, etc.), should be filled and satiated with Torah and yiras-Shamayim. Then, later on, when being amongst other people in the world, they will be able to uplift their entire surroundings by bestowing and enriching their brethren around them with the gift of ahavas Hashem, ahavas haTorah, and ahavas Yisroel in daily life.
==== Igros Kodesh V18 P168. In an address to the students of the Yeshivas Tomchei Temimim, which he founded in 5657 (1897), the Rebbe Rashab said that he desired his students to be lamplighters, to inspire and ignite the hearts of others with love and awe of our Father in Heaven, wherever they may be. “They will be,” he said, “throughout the entire world.”
