Today, Moshe Rabbeinu’s yahrzeit is an appropriate time to speak about yahrzeits of tzadikim, since all tzadikim have a part of Moshe Rabbeinu’s neshama. There are many things we can do on a tzadik’s yahrzeit that can benefit the tzadik and us. Reb Mendel of Rimanov said that the smallest neshama can do something for the biggest neshama by lighting a candle for the neshama. Imagine, by the simple act of lighting a candle l’ilui nishmas a tzadik, a simple person can benefit the soul of a tzadik.
There many other things one can do, such as give tzedaka, learn mishnayos, say Tehilim, or any other mitzvah. Before doing them you should say “I am doing this lilui nishmas the tzadiks name ben the father’s name (by certain tzadikim the minhag is to use the mother’s name). If you don’t know the full name that is also good. We owe the tzadikim for all the teachings they gave us and for all the zchusim thay may have brought to the world that we know nothing about. Also, since we did something for the tzadikim they will daven for us. Also, after 120 years if chas v’shalom one has to go to Gehinom, tzadikim have the ability to take people out of Gehinom. This concept is mentioned by meforshim in Mesechta Brochos. Among them are Tzlach(Noda B’Yehuda), Ben Ish Chai, and Rif (Ein Yaakov).
If one has the ability he can daven at the kever of the tzadik. There are many Kivrei Tzadikim in the USA Here are some in NY.
