Our thoughts are an accurate reflection of our emotions

 

When a person has thoughts of suicide, they are depressed, which Chassidus explains, as they are ashamed of themselves, hence hate themselves

 

When a person has thoughts about something they are attracted to, obviously they love or want that thing / experience etc. etc.

 

Now most importantly, if and when we are perpetually seeing bad in others, it is a sign we are angry/hate others, most often out of jealousy, for we have been raped/abused
