Dr. David Weiss has achieved world renown for his work in cancer research. Although he came from an observant home, his involvement in American culture presented him with many challenges. His encounters with the chassidim and the philosophy of Lubavitch helped him overcome these hurdles.

Once while at yechidus with the Rebbe, he asked him if he could consider himself a chassid. “I am attracted to the chassidic way of life,” he explained, “but can never see myself donning a black hat or chassidic garb. Does this disqualify me?”

The Rebbe responded, “When a Jew endeavors to take a step forward in the service of G‑d and the love of his fellow man every day, I am happy to consider him my chassid.” This is the thrust of this chapter: to share examples of how the Rebbe has personally encouraged people to advance in Jewish practice.
