If you keep the law of liberty or the principle of salvation that Savior teaches you never catch any diseases and die.
It means removing all sins in your mind and body can give immortality. Any sins come out of the consciousness of ‘I’.
Thus if you don’t be conscious of yourself, you will be free from any kinds of sin. If you do, you are definitely sinner and are going to be caught an illness.
Those who are unconscious of themselves totally have not any sickness, sins, and death. They return to persons without the consciousness of themselves. the saying that when you reach to level of without ego you will be spiritually awakened is to be completely free from any kind of sins.
Since the consciousness of ‘I’ is the root of sin not feeling myself leads to God.
