Thanks - interesting post. In my experience the description old soul is applied mostly to children, especially those who show knowledge or wisdom beyond their years - or even babies who seem to show unusual awareness and understanding. I haven't as often heard someone described as a new soul - it could have a condescending tone and I wholeheartedly support your advice against egotism and superiority.
