How can a person, who has been thinking in a negative way for a long time, change to positive thinking?

Let him start with some positive suggestive formulas: “I am hale and hearty. I am
healthy. There is nothing wrong with me. I was under a misconception of my own abilities and
capacities. Now I have realized my real nature”. Let him do it with the help of some person
advanced in Yoga or a devotee of the Lord. Let him start with a prayer to the Lord. Let him
make prayer a part of his daily life and ‘a must’ in life. All negative thinking will end and he will
become quite normal.
