The Rebbe stated that the ten psalms of Tikkun ha-Klalli are a powerful remedy for the spiritual damage caused by nocturnal emissions, particularly when recited on the same day. Reb Noson understood from his remarks that in addition, these ten psalms are an effective remedy for all sins when recited in a spirit of teshuvah.
