Discusses the Takana instituted by Chazal, to drink four cups of wine at the Pesach seder. We discuss the various reasons for this enactment. We discuss the parameters of this obligation - is it mainly to praise Hashem over a cup of wine, or is it to drink four cups of wine?

Other questions addressed include:

• Can one be motzee someone else or must each individual have his own kos?
• Must each kos be drunk at its designated time, or is it sufficient to just drink all four, one after the other?
• May one use chamar medina for the Arba Kosos?
