Perhaps it is the reality of our modern advertisement saturated media that has led many to believe that only after buying and using every product known to man, after every single penny is spent that has ever been earned in the entire history of man- and womankind then and only then will somehow perfection and happiness be possible. Somehow by doing something so unlikely to produce indestructible happiness as buying a product is more realistic than the realization that each one of us is already all we need to be. We are as complete as we need to be in order to become indestructibly happy. All we need to do is simply wake up to this reality in our lives, and the Buddha is telling us that the Lotus Sutra is the most efficacious way of doing this.
