Each Month on Erev Rosh Chodesh, which is the day before Rosh Chodesh all of the Tzadikim return “Home”. Home is their gravesites – all over the world. They return to assist us by allowing us to ask for help for the things and spiritual tools we might lack in this physical world. All we need to do is light a candle (as close to after sundown as possible) the night before or even the day of Erev Rosh Chodesh and whisper the name of the Tzadik. We can even ask for help from Kol HaTzadikim which means from All of the Tzadikim.
Go light your candles. Preferably a 25 hour candle.
