If the very foundations that we stand upon are of Love and Joy, then nothing can rock us, all is engulfed within that continuous moment of Joy/Love.
It matters not if we suddenly come to realise that an established 'truth' is false. That particular truth in which we believed enabled us at that moment in building our foundations of Joy, it is a delightful learning aid, nothing more or less and it is to be smiled, blessed and moved on from with Joy...onto the next 'truth/learning aid :)
LOL if we clung onto every belief pattern we ever held, would we not be rather confused, befuddled and mixed up by now! They would also be self defeating....If I still believed in the tooth fairy, then my children would be sleeping on piles of teeth for pillows and my whole family would still be waiting for that visit from the fairy to remove the teeth and replace them with the small packet of Joy that they are waiting for. It would make for an uncomfortable nights sleep...and a continuous waiting for that Joy to arrive!
 
No, it does not matter if tomorrow we wake to the realisation that nothing really exists, because we have built our foundations within joy and this moment of Joy shall cover all....this life, eternity. This moment of Joy can be as big, or small as one wishs to make it:)
If I waken tomorrow to the realisation that I am 'wrong' that everything i believe is untrue and that indeed I am even to descend into 'hell' because all my truths were upside down and my 'good' is indeed 'bad'....then Hell shall grow flowers, dance in Joy and shall find Love, Joy and Delighted Laughter...for that is what I am, nothing, no belief changes, no revelations and no life circumstances can change that foundation of Love. That Joy/Love moment which i exist within shall engulf truth, untruth and all in between.
I see that it does not matter which truth or anchor, learning aid or belief pattern we hold within any given moment, for when our core foundation is Love/Joy, then all else; beliefs, conditionings, patterns etc CAN be released for they simply do not matter.
They have no hold nor power over us, and we Dance with steps of Joy.
