Whatever you want in this world and obtain through hard work, then you should know if you get flowers, thorns will necessarily come along. In every pleasure and material acquisition of the world, there is nothing "thornless". With flowers, there are thorns too here. The affluent and super-achievers live in a lot of tension. They are under immense stress. In today's world, de-stressing has become the most lucrative business. The wealthy live under stress, and they want to come out of their stress and tension. The entire history tells us that if someone acquired material success in this world, they got thorns with it too. Here, with money you get anti-money. With wealth comes anti-wealth. With pleasure comes anti-pleasure. لَقَدْ خَلَقْنَا الْإِنْسَانَ فِي كَبَدٍ (90:4)

There are many such verses that inform us that a person can never distance himself or herself from sorrow. Humans can never empty themselves of tension and stress. This is the most significant truth of life that we must all know. Not knowing this reality of life leads to tension. When you realize that the world is a place where you surely get thorns with flowers, tension goes away.  When it is not possible to find a flower without thorns, or pleasure without anti-pleasure, your tension goes away.
