I have done it myself TWICE and am now posting my research to alleviate future Taekwon Masters from false information (forgive me I didn't take a screenie or video of it occuring):
1. Be sitting next to a fellow Taekwon class (boy/girl or master or soul linker), ensure both are sitting for this to work.
2. Spam /doridori slowly until you gain happy break status (Gloria Victory sign icon), there is NO need to spam /doridori afterwards.
3. Be regenerating HP (Very important to note it is not SP that needs regenerating but HP, maybe someone else will show results of it being effected by SP regen).
3.5. The HP you regenerate will be green numbers similar to the effect increase HP recovery does on the Swordsmen classes.
4. Continue regenerating till you hear the sound that soul linker buffs make when giving someone a soul link, screen goes dark as if you have been given a soul link and a personal announcement (which is not recorded in the chat bar) is given at the top screen saying that you have been given the miracle of resetting your perception locations.
The chance of it happening is very, very, very slim and exceptionally random, first time I did it, the moment I sat down with a fellow Taekwon class on the first regen HP it immediately reset, second time I had constantly sat down for 3 hours every day for 5 days.
Hope this helps to dispell some of the myths regarding this painful and lengthly process.
