pesachim 108

the strict rules about how to recline and demonstrate one's freedom.
but when does the freedom begin

(on seder night eating matzah and drinking wine should be done when reclining. important women too.... but when drinking wine only 2 of the 4 cups should be drunk while reclining. the first two or the last two? is freedom re-expereinced - slavery to freedom. or a past memory?)
