1. List you bad habits in the order of decreased importance.
2. Attack the first habit.
3. Learn Meditation in Chakra’s. Especially Ajna Chakra.
4. Meditate atleast 1 hour every day in temples/jeeva samadhi’s in Ajna Chakra.
5. Whenever there is an urge to go towards bad habits, close your eyes and see the whole cycle of urge.
6. Take the help of a meditator or spiritual guide who has treaded this path already. As Adi Shankara rightly says
Satsangathve Nithsangatvam
Nithsangathve Nirmohathvam
Nirmohatve Nischalanatvam
Nischalanatve Jeevan Mukthi.
7.At first, this will be very difficult. Thereafter, once we become a silent observer, the urge will vanish like a air bubble.
8.Keep watching this for few days, you will automatically come out of the urge.
9.Most importantly never run away from your urge or never divert your attention. Staying focussed is the key to success.
10. Every day , the first thought when we get up and last thought before we go to sleep should be that we should come out of the bad habit.
11. Pray God/Family Deities/ Forefathers whenever time permits that we should get out of the bad habit.
12.When you start with the toughest one, all others fade away like a dew drop which vanishes when the sun rises.
13.This process purifies the mind totally.
14. Ultimately, this will lead to realsing your self.
