Strength does not come from physical capacity; it comes from an indomitable will. These words of Mahatma Gandhi fit nicely into India wicketkeeper MS Dhoni's character and achievements. In 2006 after my first mental session with Dhoni during my short stint with Team India, I told coach Greg Chappell how impressed I was with Dhoni's mental skills. I also told him that I thought he could become a future captain of India.

Using an induced affect technique during that session I placed him under enormous pressure to see how well he would cope. He passed the test with flying colours. At the time, I couldn't remember any of the many athletes around the world with whom I had worked who had done better. What impressed me most was his calmness under pressure, his patience and concentration, the clarity and simplicity of his thinking, and the cool manner in which he assessed the pressure situations he faced.
