The first thing is to understand the condition of one's own body, the physical health, the mental condition; and when one can understand one's own condition better, then to begin to see the condition of another person. Then intuition is born and becomes active. As a man develops intuitively he begins to see the pains and sufferings of people; and if this sympathy grows and becomes vaster, his sight becomes more keen and he begins to observe the reason behind the complaint; and if he goes still further in the path of intuition, he begins also to see what remedy would be the best one for the person who suffers.
