אמר רבא מיחייב איניש לבסומי בפוריא עד דלא ידע בין ארור המן לברוך מרדכי
Rava said: A person is obligated to become intoxicated with wine on Purim until he is so intoxicated that he does not know how to distinguish between cursed is Haman and blessed is Mordecai.
רבה ורבי זירא עבדו סעודת פורים בהדי הדדי איבסום קם רבה שחטיה לרבי זירא למחר בעי רחמי ואחייה לשנה אמר ליה ניתי מר ונעביד סעודת פורים בהדי הדדי אמר ליה לא בכל שעתא ושעתא מתרחיש ניסא
The Gemara relates that Rabba and Rabbi Zeira prepared a Purim feast with each other, and they became intoxicated to the point that Rabba arose and slaughtered Rabbi Zeira. The next day, when he became sober and realized what he had done, Rabba asked God for mercy, and revived him. The next year, Rabba said to Rabbi Zeira: Let the Master come and let us prepare the Purim feast with each other. He said to him: Miracles do not happen each and every hour, and I do not want to undergo that experience again.
Do not attribute duality to God. Let God be solely God. If you suppose that Ein Sof emanates until a certain point, and that from that point on is outside of it, you have dualized. God forbid! Realize, rather, that Ein Sof exists in each existent. Do not say, "This is stone and not God." God forbid! Rather, all existence is God, and the stone is a thing pervaded by divinity.
