The Talmud (Berakhot 20a) records a peculiar observation: Rabbi Gidal used to sit at the entrance of the women's bathhouse. When asked how he could do such a thing — was it not immodest? — he replied: "They appear to me like white geese. I feel nothing."
The sages debated this claim. Could a man truly be so elevated that the sight of unclothed women provoked no desire whatsoever? Some accepted Rabbi Gidal's sincerity. His spiritual discipline had genuinely transcended physical desire. Others were skeptical, warning that most men should not attempt such a test.
The teaching became part of a larger discussion about the difference between the early generations of sages and later ones. The earlier sages, the Talmud suggests, had achieved a level of spiritual mastery that made them genuinely immune to temptations that would overwhelm ordinary people. They could handle situations that later sages could not.
But the Talmud also records Rabbi Yohanan, who was extraordinarily handsome, sitting near the bathhouse for a different reason entirely — so that women emerging would see him and, by gazing upon his beauty, be inspired to bear beautiful children. Rabbi Yohanan felt no impropriety in this because his intention was purely for the benefit of others.
The juxtaposition of these stories teaches a nuanced lesson: the same action can be pure or impure depending entirely on the person performing it and the intention behind it. What is permitted to the saint is forbidden to the ordinary person — not because the action differs, but because the heart does.
