The Zohar teaches that “A tzadik who departs is to be found in all worlds more than in his lifetime.” Because he is free of his corporeal limitations, the tzadik is able to grace those who connect to him with the full impact of his spiritual energies, imparting to them the love and fear of G-d, and showering them with an abundant blessing and extraordinary miracles.
