Those who pray for your downfall are concentrating negative thoughts towards you, without taking cognisance of the slippery ground in which they are standing, which could lead to their downfall.
No man ever got very high by pulling other people down. The intelligent merchant does not knock his competitors. The sensible worker does not work those who work with him. Don't knock your friends. Don't knock your enemies. Don't knock yourself.
A lie is enough to ratify you are a liar. Lies assist people to forget about the things you have done in the past and remain persistent for whole future as a huge doubt.
