Mikveh Immersion for Men

Hello, You are asking about the immersion in a mikveh for men, and the answer will address only men. There is no difference between Sephardim and Ashkenazim. Before entering the mikveh, it is important to wash the body of dirt and sweat, as others will enter the mikveh after you, and it is essential to enter the mikveh clean. You can immerse as many times as you want, with each immersion adding purity (the common custom is to immerse four times). The immersion should be such that the entire body is in the water without holding onto anything inside or outside the water. After coming out, you can shower, as this does not invalidate the immersion. There is no blessing for the immersion. After immersion, one should wash their hands. According to the Arizal, it is advisable to recite the verse "Create for me a pure heart, O God, and renew a steadfast spirit within me." In the book "Bnei Yaakov" (Vol. 2, page 294), the words of the Shelah HaKadosh regarding immersion in a mikveh are brought: "The virtue of immersion is to restore the soul to its place, for one who is impure does not have a soul. Particularly one who blemished the sacred covenant; his soul departs from him, and even if he repents, the soul does not return to him until he immerses in a kosher mikveh. Every person needs immersion every Erev Shabbat to remove the garment of weekday spirit and wear the sanctity of Shabbat, as explained in the Zohar (Vayakhel)." Good luck and all the best.
