According to Osho, if darkness is seen, your eyes are alive—so light is inevitable. Darkness and light are degrees; shift attention from lack to gratitude for seeing, and dawn begins. Dense night means morning is near. Start by admitting 'I am ignorant,' letting the ego dissolve; in that inner space, the divine ray appears.
If you can notice darkness inside, be glad you can see, say “I don’t know,” relax your ego, and the light will come by itself.
