When you break up with someone or if someone close to you dies, you will keep remembering them whenever you see their belongings or patterns.
There is a process called conditioning through which, two unrelated things get linked. Pavlov experimented on dog. He rang the bell always before giving food to dog. So dog got conditioned and paired bell sound with food. So it started salivating, on hearing bell, even though there is no food.
It is so strange that humans also get conditioned to remember person on seeing their belongings. Dont you think that you are superior to pavlov dog?
Break the conditioning pattern by rewriting the memories. Dont remain forever as slaves of conditioning.
Eg: imagine you had a breakup and there is a place which reminds you your ex. Dont run away from place. Instead, rewrite memories by going to place with some other person!
