As explained earlier, there are two opinions as to when we are obliged to begin studying the laws of Pesach and teaching them to the public. According to one view, we begin thirty days in advance; according to the second view, we begin from Rosh Chodesh Nissan, just two weeks before Pesach.
The Rebbe explained that although the law follows the first viewpoint, we should nevertheless take the second opinion into account as well and greatly increase the quantity and quality of our study upon reaching Rosh Chodesh. Just as there are two opinions expressed concerning the time to begin studying the laws of Pesach (and in practice, we should follow both of them), so should we apply both views to our providing Maos Chitim and all the other requirements for Pesach.
