How can you become old in spirit? Only by carrying the past, isn't it? If you carry sixty years of burden with you, you're sixty years old. If you don't carry anything, you're like a newborn. The physical body may develop limitations, but the way you are has no limitations. It simply has no limitations. You are this many years old or that many years old simply because you carry that many years of garbage with you.
