In 5751, rosh chodesh Nisan occurred on Shabbos Parshas Vayikra. Three sifrei Torah were taken out. The first one was taken out for the regular parsha, the second in honor of rosh chodesh, and the third for parshas hachodesh that's read as we approach the new month of Nisan. Three sifrei Torah are taken out every year on Simchas Torah. Occasionally we read 3 parshios together, such as when rosh chodesh Nisan occurs on Shabbos.
The Rebbe Shlita Melech Hamoshiach says that we have to learn something and apply it in our every day life when we see sifrei Torah taken out of the ark.
When the ark is opened up we say the posuk "Vayehi binsoa hoaron... Kuma Hashem..." The posuk teaches us a number of things. First of all, each and every one of us has a "Moshe" in our hearts. We are all connected to the Rebbe Melech Hamoshiach, the Moshe of our generation. When we open the ark, the "Moshe" within us says "...Kuma Hashem..." Do more mitzvos and bring more holiness into the world. The posuk continues, "...Viyofutzu oiyvecha..." This means that we should get rid of all the bad things from within us. When we take out 3 sifrei Torah, we have the strength to continue doing good things.
This special event of taking out 3 sifrei Torah happens every couple of years, but the horaa for us is to always continue doing good things.
