According to Osho, tears begin to flow because bliss and love arise when your heart attunes to the master's in satsang; language fails, restraints dissolve, and the overflowing feeling finds its most innocent prayer in tears. They are not helplessness but a sacred expression, a rain from heavy clouds of longing—an auspicious sign that your heart is awakening.
Your heart is so full of love and joy that words can’t say it, so your eyes say it with tears.
