According to Osho, when unhappiness drops and happiness flowers, a 'window of the heart' opens: you awaken from your habitual mind, your rhythm falls in tune with existence, and a clear, luminous depth is revealed. For a moment the ego evaporates and reality is known in a new, qualitative way. If you don't heed the doubting mind, such glimpses grow, become abiding, and the old world feels illusory.
It’s like an inner window opens, everything feels bright and connected, and if you trust it instead of doubting, it lasts longer.
