In some ways it damages the culture and promotes changes which would otherwise be unacceptable. It also provides an income and a good living for many Balinese. Those of us who earn our living in this way should be able to express our thanks to the Gods and return some of our profits to the people who contributed them. It is another cycle. We take and give, we give and take.
Cycles are the key to understanding Balinese culture.
As long as the cycle continues the body and the soul will be nourished. The feet must nourish the body. The body must nourish the soul. When the elements are in balance the cycle will be maintained. A good product does not need advertisement.
