There is a custom to light bonfires in honor of Rashbi. The souls of all the tzadikim are there when the fire is lit. There is a custom to put olive oil in the fire and to burn clothes in the fire. The Rizhiner used to send silk garments to Miron to be burnt in the bonfire. Tzadikim of Eretz Yisroel say this is a segula for success, materially and spiritually.
