Let’s imagine that today you are meeting the real Buddha for the first time in some temple in the mountains. You are looking at your notes one last time; you have your questions rehearsed. It’s time to get into the car. Several hours later you make it to the temple. It’s still morning. Everything is beautiful outside of the temple. You’re quite nervous but still manage to relax.
The moment has arrived when you get to meet this Buddha. Finally, all your questions will be answered to your satisfaction. This is a dream come true for you. But all that transpires is seeing the Buddha sit looking at you. Pleasantries are exchanged, of course, but that is all. The Buddha just sits there and now you begin to feel awkward. Then you interrupt the silence to ask your first question, “What is enlightenment?” Still the Buddha doesn’t say a word. He just sits there.
So what is really going on? It’s simple. The Buddha is radiating what could be described as the light of Mahayana mentioned in the Lankavatara Sutra or if you prefer he is radiating clear light Mind. But here is the rub. You sense absolutely nothing, zero, zip, zilch, nada. Why? Because you are spiritually blind that’s why. You are only connected with your conditioned psychophysical body and the temporal order—that’s it. Your questions and what you believe Buddhism to be have nothing to do with what the Buddha is radiating (which you don’t sense). But more importantly, what he is radiating is the teaching! He can’t help but radiate this mysterious light. He is like the sun in the sky shining on all things.
After you’ve seen the Buddha, the head monk says to you, “When I first met the Buddha I was so blissed out I could only bow. It was amazing. It is still that way every time I come near him. More and more I am learning about it.” You don’t know what to say to the head monk because you sensed nothing. The head monk could be pulling your leg for all you know.
Everything in the teachings of the Buddha is designed to get you to understand this light from its own side which you converge with during awakening — the Mind to Mind transmission which is spoken about in Zen. In fact, when the Buddha held up a flower and blinked whereupon Kashyapa smiled, both their actions were only a manifestation of this light in the same way that smoke tells us there is fire somewhere. Both were fully one with the light. According to the Avatamsaka Sutra: Manifesting spiritual power while among the masses, he [the Buddha] radiates light to make them wake up, revealing the realm of the enlightened.
