Man, by his thoughts, makes his nature. When he says, "I cannot agree with this", he will not agree with it; he has made a wall before himself. When he says, "I cannot bear that person", once he has said it, he has created something in himself which makes him sick when that person comes to him. That person becomes his master. The man wants to run away from him; wherever that person comes, he makes him ill. It is not because that person brings him illness: the man has brought that illness upon himself.
