How can a Jew tell if he or she is growing spiritually? If you are not seeing visions, if your prayers are not being answered immediately, if your spiritual life seems to be pretty much the same as it has been, then how can you know if you are moving up the spiritual ladder?
One very good measure is if you see that your love for your fellow Jew is increasing. When you see a Jew you never saw before, and you feel family… you know that you are growing spiritually... this is one of the results of fulfilling the commandment, "You shall be holy…."[i]
