Tikkun Shovavim
A Tikkun is a fixing of a sin. When one sins a part of their soul and life force is captured by the Sitra Achra (lit. other side). The person’s life force will stay there until it will be taken out and brought back to Kedushah.
In Shaar Ruach Hakodesh the Ariza"l writes about many sins and how to do Tikkunim (plural for Tikkun) for them, thereby getting back the parts of soul and life force. It’s very important that one does the full Tikkun of his soul before he passes away from this world so he doesn’t need to suffer to cleanse himself.
Before going into the specifics, one important point must be made. These Tikkunim are for the correction of the soul. This does not mean that it is instead of Teshuva. You must also do teshuva along with the Tikkun. The Tikkunim are for after you have already done teshuva and you now want to fix your soul.
The basis of the tikkunim is to fast. For each sin, there is a prescribed amount of fast days. While fasting is an important part of the cleansing process (and helps a lot), they don’t need to be done if a person is weak or sick.(pease check with your doctor to see if it is safe to fast) Nevertheless, those that are able should do it.
These fasts do not need to be done consecutively. Each fast if from Alos Hashachar until Tzeis Hakochavim. (Before sunrise until nightfall.)
