All of these activities should be designed to draw large crowds.
LAG B’OMER PARADES
We should strive to arrange Lag B’Omer Parades in each and every location – as has indeed been done over the past few years.
THEME: JEWRY IS PARADING FORWARD AND UPWARDS
The purpose of these Parades (or “Tahaluchos,” as they are known) is to emphasize and display openly – for the entire world to see – that the Jewish people are parading forwards (holchim) to fulfill the will of their Creator.
Moreover, our advance takes the form of constantly traveling upwards (halichah) from one level to the next.
