All habits originate from the subconscious plane. Subconscious life is more powerful than your ordinary life of objective consciousness. Through the practice of Yoga you can modify, control and influence the subconscious depths. Take one evil trait. Meditate on its opposite virtue every morning. Practice it during the day. The evil quality will vanish soon. Meditate on mercy in the morning and practice it during the day. You will soon develop mercy.
