The fifth Lubavitcher Rebbe, the Rabbi Sholom DovBer, once told the his son, the Previous Lubavitcher Rebbe:
“Yosef Yitzchok, during the Seder, and especially when opening the door for Eliyahu Hanavi, one must think about being a “mentch” and Hashem will help. Don’t ask for the physical, (ask) only for the spiritual.”
(Sichos Chag HaPesach 5702)
