The only greatest error of man is that after reaching this highest state of evolution to complete the journey, he or she is strangled in the world. This is because of the wrong use of the intellect. Instead of moving towards awareness to get to the state of consciousness (Self-Realization), man has used to go the opposite direction of the mind towards sense objects. Because of this attitude we keep undergoing the same rebirth and death cycle to fulfill our desires.

      Evolution is a forward process. It is natural law that any inhibition will be fought against and move towards freedom. Since evolution progressed as a result of unfavorable survival conditions overcoming inhibitions, we also try to overcome life short comings through constant fight. But we are meeting failures because of the the lack of correct understanding about life. We are not here to extend the length of our lifespan and enjoy the sensual world, instead we are to complete our destination, Journey to the Source.

   When we fail to move forward, then nature itself pushes us giving us hard lessons in life. Then in this struggle only the intelligent survives.   Evolution is a process driven with the power of "Survival of fittest". Who survives? The one with more intellect which can use its body power to withstand hardships and challenges and which can adapt to all hostile conditions and not to yield to the environment. The design of the evolution is already destined and the question of free will emerges gradually emerges but is well established in human only. Rest of the beings are sort of pre-programmed. But human have free will, the choice making freedom and has the choice to time his final destination to Source. Instead of using our free will to reach the final destination the way we want, we are misusing the free will to being stagnated in the sensory world.
