– Q. Can you make a siyum for a Yohrzait of parents when you finish learning an important sefer, such as Mesilas Yeshorim or similar?

A. Usually the common Siyum is on a Talmud volume, a Mishna sefer, or a book of Tanach. However, Horav Shlomo Miller’s Shlit”a opinion is that if it was indeed learned properly and with true understanding and perception, a siyum could be done.
Horav Shlomo Shlit”a  added that one should consult directly with a capable and competent Rov, that can judge and evaluate the learning conditions and the achievement obtained.
