It means your mind is totally quiet and clear like light, not busy being clever—just simply aware.

Osho, what is the first experience of samadhi like?
You will know only when it happens. It cannot be said; at most a few hints can be given. It is as if, in the dark, a lamp is suddenly lit. Or as if a dying patient, right at the edge of death, suddenly finds a medicine that works; life’s wave, life’s thrill spreads again—so it is. As if a corpse becomes alive—such is the first experience of samadhi. It is the taste of nectar. The experience of the ultimate music. But it will be only when it happens; and only then will you understand. You will not understand by my saying it. It is as with love. How can anyone explain it? To someone who has never loved, never known love, no matter how many explanations you offer—he will hear it all and still ask, “I haven’t understood; please explain a little more.” It is like explaining light to…
तीसरा प्रश्न: ओशो, समाधि का पहला अनुभव कैसा होता है?
होगा तो ही जानोगे। कहा जा सके, ऐसा नहीं है। कुछ-कुछ इशारे किये जा सकते हैं। जैसे अंधेरे में अचानक दीया जल जाये, ऐसा होता है। या जैसे बीमार मरता हो और अचानक कोई दवा लग जाये...मरते-मरते कोई दवा लग जाये; और जीवन की लहर, जीवन की पुलक फिर फैल जाये--ऐसा होता है। जैसे कोई मुर्दा जिंदा हो जाये--ऐसा होता है समाधि का पहला अनुभव। अमृत का अनुभव है। परम संगीत का अनुभव है। पर होगा तो ही होगा। और होगा तो ही तुम समझ पाओगे; मेरे कहने से समझ में न आ सकेगा। प्रेम में जैसा होता है। अब कोई किसी को कैसे समझाये? …
Kindly explain the relative importance of intellect, intuition, and pratibha in their proper perspective. Pray, specially explain why and how life should be pratibha-oriented and how only such an orientation is adequate for life and life's evolution at its highest and best.
The intellect is the lowest functioning of your being, but because it is the lowest, it is the most efficient. Because it is the lowest, it is the most developed. Because it is the lowest, it can be educated, disciplined. Because it is the lowest, all the universities, colleges, schools, exist for it. And every man has it more or less. It is tremendously useful in the outer world. Without intellect it will be difficult for you to be of any utility. That's why Lao Tzu says to his disciples, "Become useless." Unless you are ready to become useless you will not be ready to leave intellect behind, because intellect gives you utility. You become a doctor -- you become useful to the society. You become an engineer, you become a professor -- this and that. It is through intellect that you become somebody and the society can use you…
The other is a child of light, which means a child of god, because god is light. Down the ages light has been the metaphor for god. Both meanings are joined together, both come from Persian. To be a child of light, to be a child of god, is to be precious, 'Without god there is no value in life. Unless we are related to god, unless there is god, there is no significance in life. Without god life is only accidental, a mundane affair: a tale told by an idiot, full of fury and noise, signifying nothing. But if god is there then everything becomes meaningful; god becomes the context in which everything gains meaning, becomes precious. Without god we are orphans, the whole existence is an orphan. With god existence is a home. Then we are children of god.
These samadhis that result from meditation on an object are samadhis with seed, and do not give freedom from the cycle of rebirth. On attaining the utmost purity of the nirvichara stage of samadhi, there is a dawning of the spiritual light.
IN NIRVICHARA SAMADHI, THE CONSCIOUSNESS IS FILLED WITH TRUTH. ... For example if you contemplate on emptiness; the object is almost not, if you meditate on nothingness. There are Buddhist schools which emphasize only one meditation, and that is on nothingness. One has to think, one has to meditate, one has to imbibe the idea that nothing exists. Continuously meditating on nothingness, a moment comes when the object becomes so subtle that it cannot withhold your attention; it is so subtle that there is nothing to contemplate, and one goes on and on and on. Suddenly, one day the consciousness bounces upon oneself. Not finding any standing ground there in the object, not finding any foothold, not finding anything to cling to, the consciousness bounces upon itself. It returns, comes back to its own center. Then it becomes the highest, the purest, nirvichara. The highest, nirvichara, is when the consciousness bounces
