It's not as much the ignorance of your Sacred Sound Healing System knowledge, as often it is the knowledge of your own ignorance of who you really are - the cause of All problems. Without relativity you wouldn't realize your true self & also wouldn't admire the creation of nature.
Only when you see the not so good things in life, you start admiring the good things in life. That's the law of nature & that's why nature has created so much of contrast in life. It is supposed to be designed that way.
Also again, the definition of good is relative & subjective & hence our experiences differ based on our perceptions of what is good & what is bad in our lives. How can you appreciate the good in life without being aware of the presence of the 'not so good'?
And that's why diseases, earthquakes, famines, disasters & other such terrible things exist in life. They exist to help us remain aware of the contrast in our life.
