The source of something is very important to where you are in this moment; what you think, believe, love, have faith in etc. To that point, someone said to me after I asked a question, "Don't try and move me." Move them from where? Comfort, belief or faith? The statement is a defense mechanism or security reaction which I inadvertently triggered.
A secure reaction comes from the instability of mind and why it wants to remain where it is (bound in belief). Because the mind is doubtful without a secure place to move to which is away from the minds source-reality of belief, value, faith, promise etc.
Thereby if the mind is the source - a collection of fragmented thoughts - then doubt, desire, fear and uncertainty replicate within the recipient (next generation/mind) that reality.
