Michael Laitman explained that the strength of a lie is in its concealment. If a lie is revealed (that it's a lie), it's abandoned, bringing us to the truth. A lie wants to remain concealed/hidden because that's how it continues to exist. As a lie spreads, as more people use it, buy into it and engage in it, eventually they realize that they have nothing, that it's a lie. The lie is then abandoned, bringing us to the truth. The lie brings about its own death, specifically, the widespread use of a lie, brings about its own death. In a world of lies, it is lies that bring us to The Truth.
He went on to give an example: Let's say a company manufactures a product that's not that great. They sell a few here and there and make some money. Eventually, they want to make more money, so they advertise to sell more. More people buy the product and discover that it's not that great. People stop buying the product and the company goes bankrupt.
Based on that explanation, let's take a look at our society. We've built a society that's based on a lie - that the quality of selfishness will fulfill us. The widespread use of this lie, all the many ways that we're selfish, is bringing about its own death because we're beginning to realize that we have nothing, that we remain empty, unfulfilled and unhappy. Eventually, the lie (selfishness) will be abandoned, bringing us to The Truth - that our happiness and fulfillment comes from connection, from unity and from doing good to others/Nature instead of ourselves. By this, we'll reach harmony and balance with each other and with all of Nature.
