Theory of rebirth

Few religions take into consideration the concept of reincarnation. So here is my take on that.

Thoughts are very unique and one of the things that is immortal. When a person dies, his thoughts remain in the world in the form of memories in the minds of his dear ones. Even in his enemies in the form of negative thoughts. Thoughts take the shape of personalities and its the personality which makes us feel he resembles someone from the past.

Suppose the great scientist Newton has had several thoughts that became part of his personality. In a very rare situation, there may be a person born who has similar thoughts and thus very similar personality. People assume that he is reincarnation of Newton. But in reality, the person may have picked up Newton's thoughts and hence has developed personality traits resembling Newton.

Reincartion is just transfer of thoughts of a person belonging to different time and place to another person who is born in different time and place.

Also when we say a person will be reborn as an animal. It represents that his deed emerging out of his thoughts were like animal(senseless and menacing) and hence in rebirth he will be an animal.
Thus metaphorically again representing transfer of thoughts.
