For 21 days, Laugh for 3 hours a day for 7 days, shed tears for 3 hours a day for 7 days, and then sit silently for 3 hours a day for 7 days.
The course includes OSHO Dynamic Meditation during the 3rd week and optionally for the first two weeks, in addition to OSHO Kundalini Meditation and talks.
Whenever any experience is not fully lived in the moment, it leaves a residue inside us. It may be a small thing or something really significant but those residues or scars stay in the unconscious blocking our natural ability to flower to our full potential.

“I have invented many meditations, but perhaps this will be the most essential and fundamental one.”
Osho
Laugh, Cry, and Let the Scars of the Past Be Dissolved in Silence

Whatever is left in the unconscious remains, waiting for an opportunity to be expressed, accepted, and resolved.
When we allow all our un-laughed laughter, our un-cried tears, and our un-lived silence to be experienced, we can allow whatever is in the unconscious to flow freely and be lived now – and be resolved forever.
The laughter, tears and silence do their work without the need for words, discussion, or analysis as is typical of conventional “therapy.” You just participate with totality and sincerity, and the rest happens by itself.
The OSHO Mystic Rose provides that opportunity.
As Osho explains:
For seven days we laugh for no reason at all for three hours each day.
“The first part… for three hours, people simply laugh for no reason at all…. Digging for three hours you will be surprised how many layers of dust have gathered upon your being. It will cut them like a sword, in one blow. For seven days continuously, three hours every day… you cannot conceive how much transformation can come to your being.”
“When a man reaches into his innermost being he will find the first layer is of laughter and the second layer is of agony, tears.”
For the second seven days, we cry for no reason at all for three hours a day.
“So for seven days you have to allow yourself to weep, cry, for no reason at all – just the tears are ready to come.”
“The first part removes everything that hinders your laughter – all the inhibitions of past humanity, all the repressions. It cuts them away. It brings a new space within you, but still you have to go a few steps more to reach the temple of your being, because you have suppressed so much sadness, so much despair, so much anxiety, so many tears – they are all there, covering you and destroying your beauty, your grace, your joy.”
The third part is the time for the “Watcher on the Hill,” just watching whatever is happening inside or out.
“And my effort here is to take away all your scars and all your wounds and make you aware that you are just a watcher. A watcher cannot be wounded; no bullet can pass through it, no nuclear bomb can destroy it.”
“Just be a witness. Go on witnessing whatsoever passes in the mind, and the very process of witnessing has the whole secret in it.”
“Then you know that you are just the quality of reflection, that you are a pure consciousness, a witness, that you are a mirror and nothing else, that you are just a watcher, a watcher on the hill.”
“That is freedom. That’s what is called liberation, nirvana. And that man knows what benediction is!”
“This is absolutely my meditation.”
