The French philosopher Michel de Montaigne is quoted as having once said ‘The greatest thing in the world is to know how to belong to oneself.’ Never is this truer in our current, fast-paced society, where our obsession with worldly desires overwhelms our daily lives. This is the reason why the practice of meditation had survived through the evolution of humanity.
As life found a way to grow and thrive mind and its consciousness found a way of their own. Because not always are our obsessions a driving force for our passions and goals. Sometimes they consume the mind and like a dried-out barren land that was once fertile enough for new plants, the mind can no longer brew new and positive thoughts.
To rid of these obsessive thoughts means to renew the minds co'gnitive powers and give your life a fresh start. Letting go of our obsessive thoughts gives us freedom, and freedom is the only condition for happiness.
The best way to free yourself from these obsessive thoughts is to meditate on the impermanence of worldly possessions and desires.
To meditate on impermanence is easy: simply contemplate the fact that nothing lasts forever. The trees, the buildings, the people, and all the other things we hold on to dearly will someday die. Think deeply about this fact, and imagine watching as these things wither away and pass.
Also, meditate on how everything lives on in a different form. If a carcass sits on the dirt, it eventually decomposes and sifts into the soil, becoming a part of it. In very much the same way, we and everything else around us live on in a different form after we pass.
