Naturally fallen from higher to lower. Then you make progress, again come to this human being. This is a via media with good consciousness. If you utilize your good consciousness, then you go still higher, you go to God. But if you don't use your higher consciousness, then again go to down.
This is going on, cycle of birth and death. This human form of life is meant for self-realization, God realization. If you don't use properly our this life for God consciousness or Kṛṣṇa consciousness and go back to the kingdom of God, then we have to suffer again in the 8,400,000 species of life cycle, one after another. That is our choice.
So the best choice is to take to Kṛṣṇa consciousness, or God consciousness, and your life is perfect. Don't be misguided. Take to God consciousness, Kṛṣṇa consciousness, and your life . . . then it will be proper use of this human form of life. Otherwise, if we indulge in meat-eating like tiger, I may get life like a tiger next life, but where is the use?
