In memory of Rabbi Levi Yitzchok ben R' Zalman Yuda Deitsch OBM
If we would truly want it we could effect the coming of Moshiach now. Then we could celebrate the holiday of Lag B'Omer with the Rashbi himself. As it says in the Zohar that the righteous will be the first to rise, which will occur immediately after the coming of Moshiach. In addition, the Holy Temple also will have to be built immediately. In order for this to occur we will have to personally ask Moses and Aron, who already had the Holy Temple in their days, how to build it.
