It can convert an enemy into a friend, a moment into years, a hell into heaven and man into Almighty. The philosophy of Ayurveda stresses the importance of utilising mind, the most powerful instrument of man as given in the following prayer:

From unreal, lead me to the real

From darkness, lead me to light

Form ignorance, lead me to knowledge

From death, lead me to immortality
