Many have a custom to give children toy bows and arrows to play with at Lag BaOmer picnics. The Bnei Yissachar cites an explanation from one of his teachers that, as a result of Rabbi Shimon’s great merits, no rainbow was seen during his lifetime. (According to Torah, the rainbow is a sign of G‑d’s displeasure.) We play with bows to commemorate this miracle.
Another reason is based on the teaching of the Zohar that there will be an extremely bright, vivid rainbow before Moshiach comes. This is connected to Lag BaOmer because Rabbi Yisrael Baal Shem Tov, founder of the chassidic movement, taught that learning the mystical dimension of Torah espoused by Rabbi Shimon brings the messianic era closer. We play with a bow to remind us of the imminent arrival of Moshiach.

Any success we may have against the “murderous” tendencies of the yetzer hara may be the result of Divine help that we failed to ask for, but received anyhow. The mistake, many have found, is to ascribe spiritual greatness to their own efforts. It takes but one time for GD to hold back His help for a person to find out how easily and quickly they can fall prey to their yetzer hara’s machinations. A lot of great people have done so, and never realized it until right before death itself.
So, ask for GD’s help. That’s what Rebbe Elimelech of Lizhensk did in his song. He recognized how strong the yetzer hara is, especially when it comes to disparaging other people. He did not rely upon his own spiritual greatness to win that battle. He turned to GD for help, and the record shows he got it. His kindness to others is legendary.
