How to pursue spiritual advancement in an extremely materialistic world?

In this age of materialism, I believe that the most valuable spirit is: to be pure of heart. It is to keep oneself pure in heart and to have fewer desires. As a human being comes to the world, absolutely no desire is impossible, and desire is not always related to fame and status. To be pure of heart is to maintain a good state of mind, not to be attached to anything, not to blindly pursue and compare, and not to seize fame and fortune regardless of the consequences. Emotions are born from the heart, the situation follows the heart. What kind of mentality, will do what kind of things. For example, there are many people see other people make money in the stock market and get rich, but also do not consider whether they have the time and energy to invest; can not in the stock market "long-sleeved dance", to master its certain rules; there is no adequate psychological capacity, they will blindly follow the trend regardless of all the results of the loss of a mess, the usual scrimping on food and clothing money lost in all. There are also in the stock market once the market is optimistic, and not in time to stop, and produce a desire to earn some more, as a result, "the sky is the limit", the stock market all of a sudden by the "bull" to "bear", From "red" to "green", and from then on was the stock market "trap".
