Greetings and blessings,
In the advent of the upcoming Pesach holiday, I would like to extend my wishes that you celebrate the holiday in a kosher and joyous manner with all the members of your household. May you merit to have an influence on all those who live in your surroundings that they advance higher in spiritual matters on the path that ascends to the house of G‑d.
In particular, this applies during the days of the Pesach holiday which marks the beginning of the “conversion” of our people. Every year, on the festivals, the spiritual concepts relevant to them are aroused [anew]. Pesach is “the Season of our Freedom,” not only from physical enslavement, but from the yetzer hara. The lesson of the day is to add strength and activity in [our Divine service related to] these concepts. For this reason, matzah is called “the bread of healing” (Zohar, Vol. III, p. 183b) and it strengthens faith, as stated there (ibid., p. 41a).
Enclosed is the kuntres published for the Pesach holiday which will certainly interest you.
Take note regarding the concepts that I cite in my introduction:1 that when eating matzah on Pesach, the body derives nurture from food that strengthens faith in G‑d. Note also that the Paschal sacrifice is different from other sacrifices in that, from the outset, it is brought for the sake of being eaten,2 i.e., to be eaten by the owners rather than consumed by the Altar’s [pyre] or eaten by the priests.
With blessings for a kosher and joyous holiday,
M. Schneerson



The idea of freedom deserves to be better described and properly understood. Freedom comes with license or the need to limit freedom when it does harm to somebody else.
These days freedom is so widely used as a term for doing what one chooses, without paying regard to how it affects others, that instead of using it as one word we should use it as half of a two-word expression to include license too,
We do not have the right to express our freedom when it causes difficulty to others, That is what Hillel's corollary is to "love your neighbor as yourself" is all about. Don't do offense to others when you would be offended were it being done to you, (even if it is inadvertently of course!).
