The book by the Spanish philosopher D.S. Guzman talks about Maya, an ancient eastern deity who embodies Illusion. We are talking about a veil behind which Nature hides the essence of all things and phenomena, so that we humans cannot too easily comprehend its hidden laws. Maya performs an important function - it points out what is not genuine, what really does not exist, what lives no longer than a flash of light, what is just dust in comparison with the Great Being, with the Great Truth... Maya - this is a mirror. She is neither good nor bad... One day a person will become so perfect that she will no longer be needed. But for now we still need to know her tricks and traps so as not to fall into her web of illusion so often.
