22 Adar I, 5774 (2/22/14) – Sukkah#19 {Eliezer}
R’ Yitzchak ben Elyashiv: Pourable Mud combines to complete 40 se’ah of a Mikvah, but if dunked in that substance within the Mikvah, not valid immersion.
E’s Lesson: Just because something can be USED for a good purpose, does not mean that the thing Itself is something Acceptable for everything. Be careful what you deal with and always ONLY use things in a positive correct way.
