Mangal teen mein jo tu apne gusse pe na kaabu payega, poonch mein laga ke aag apni hi lanka jalayega.
With Mars in the 3rd, if you do not control your anger, you will set fire to your own tail and burn down your own Lanka.
Continuing with Mars in the 3rd house, Dr. Sharma issues a severe warning for when this placement turns negative.
Mars is pure fire. In the 3rd house of courage, if the person lacks emotional maturity, this courage turns into blind, destructive rage. Dr. Sharma uses the metaphor of Lord Hanuman burning Lanka. But in this case, the person's anger is so blind that they set fire to their own tail and end up destroying their own empire ("apni hi lanka jalayega").
If you have Mars in the 3rd house, your greatest enemy is not outside; it is your own temper. Control your anger, or it will burn your career and relationships to ashes.
