The mind is like an elastic band. The more you pull, the more it stretches. The mind-elastic will never break. Every time you feel limitations, close your eyes and say to yourself, 'I am the Infinite,' and you will see what power you have.
If you have a strong desire for recovery, and doctors are giving you no hope, it is logical that you would turn to alternative approaches where hope is not only allowed but encouraged, for there is much evidence to show that people can recover from supposedly 'incurable' diseases.
