Here's something from Lao Tzu's Hua Hu Jing
Thirty-FiveIntellectual knowledge exists in and out of the brain.
Because the brain is part of the body,which must one day expire, this collection of facts, however large and impressive, will expire as well.
Insight, however, is a function of the spirit.
Because your spirit follows you through cycle after cycle of life, death, and rebirth, you have the opportunity of cultivating insight in an ongoing fashion.
Refined over time, insight becomes pure, constant, and unwavering.
This is the beginning of immortality.
I take that to mean that any spiritual development or progress you make will be with you always. So while some people may have progressed further in their psychic abilities in a past life, thus appearing to be a 'natural-born' psychic in this life, the reality is that we all have these abilities, it's just that we're not all equally in tune with spirit.
