Mitzvah Mindfulness Mandated?

In its initial analysis of the Mishnah, a great sage presumed to have uncovered the answer to a question that had long baffled the sages: must a mitzvah be performed intentionally, or can meaning be attributed to mindless actions? The Talmud engages in rigorous, its unique signature give-and-take, to meticulously analyze the supposition and frame it in the precision-driven syntax our sages employed. Although ultimately, the supposition is dismissed, the analysis is illuminating, revealing and instructive on many levels as we emerge with a clearer understanding of the Seder etiquette and the thought invested into each detail of its revered rituals.
