life is nothing but knowledge. without knowledge the life is like death.Once the aspect of knowledge is removed, the life is useless and can be controlled by anybody.

The english sentence gragment contruction does not seem correct - grammatically as well as logic wise. Can you please provide the complete sentence and the preceding and succeeding context so we can help you better. To me this seems to imply 'death means freedom from the dhyas=knoweldge (or awareness) of the deha=physical body (sense of individuality) and once you have detached yourself from the body, then you will experience real life.' I tend to think this is more on the spiritual side then on the worldly.
