Only through understanding it can be liberated, otherwise it finds itself again bonded to the chain. This liberation is possible only though human life. That's the purpose of human. There cannot be any other evolution to any other form, which at least cannot be thought through the limitations of human brain. Break the chains of life and death through proper understanding.
Spirit of life is the nature of man.
Being spiritual is the desire for this freedom from bondage. Unfortunately this spiritualism is commercialized by the greedy man and hence it becomes a religion which is the lock to the chain of life and death. Hence one should be spiritual and not religious. Being religious never takes any one anywhere, but getting tied to notions and many more beliefs. The highest evolution of man could be to that step of being spiritual.
