One takes less than a kazayit (the size of an olive) of karpas - so that he not become obligated to recite a final blessing for it - and recites the blessing, "who creates the fruit of the ground," upon it and dips it in vinegar. Then he eats it without reclining, which is as was written by the Gaon, Chida (Chaim Yosef David Azulay); and also like our custom from the time of the crown of my head, the teacher and Gaon, my master grandfather, may his memory be for life in the world to come - to eat it without reclining. And this first dipping, which is the karpas in vinegar, is a remembrance of the cause for the hardship of the subjugation - as it was because of the sale of the righteous Yosef; that they dipped his cloak of pasim into blood, sold him and caused anguish to our father, Yaakov, may his memory be blessed. And this is hinted to in (the word,) karpas. And that is since the letters, kar, are the end of makhar (sold), and the letters, pas, are the beginning of pasim. And the second dipping, which is the bitter herbs (maror) in charoset, is a remembrance of the hardship of the subjugation itself. As they embittered (mararu) their lives with the work of clay, which is hinted to by the charoset, as I have written about in my small book, Mikabtze'el. And even though we said that one needs to take less than a kazayit of karpas, so that he not become obligated to recite a final blessing for it - behold, if he erred and ate a kazayit, he needs to recite the blessing, "who created many souls," after it. Nevertheless, he does not recite the blessing, "who creates the fruit of the ground," upon bitter herbs, since it is considered something needed for the meal that comes within the meal (and hence covered by the earlier blessing over the matzah). And he should take care not to eat all of the karpas in the Seder plate, but rather leave some of the karpas in the Seder plate until after [eating from the matzah]. As the secret of the Seder plate needs to be complete until after the eating of matzah and bitter herbs.
