Picture the sun. When thick cloud comes over, the sun is no longer visible. But it has not broken, and it has not gone out. When the cloud clears and the light comes through, the sun has not been newly born either. What was there all along has simply become visible again.
The buddha at the very source of Shingon Buddhism is called Mahāvairocana — Dainichi Nyorai, the Great Sun. This buddha's light is stopped by no cloud and no night, and it reaches the living and the dead alike.
The sun in our sky, mind you, falls far short as a likeness. It is only a little alike, and for that we add the word “Great,” as the old commentary on the Mahāvairocana Sutra explains.
Why can we say it reaches even the dead? Picture a torch. Only what you point it at is lit, and everywhere else falls into shadow, because it shines from outside. There is a distance, there is a direction, and some places are simply never reached.
Daylight is not like that. It does not come at you from one point. The sky, the sea, your own hand are all simply within the brightness, and even the shaded side of things never goes pitch dark. This buddha's light is nearer to that. It is not aimed at you from outside; it was already filling everything. The life of this world and all that has shape, Shingon Buddhism says, is this buddha's own form, entire. So there is nowhere the light does not fall.
That person is within that light. So are you, right now. Being in the same light, there is no far and no near. It was never a question of how far the light carries. It is a matter of never having been apart. Becoming invisible and ceasing to exist are two different things.
On the distance between buddhas and ourselves, Kōbō Daishi Kūkai writes as follows. The phrasing is difficult, so feel free to let your eyes slide past it. I will put it in one line immediately after.
- Translation
- That body is precisely this body, and this body is precisely that body. The body of a buddha is the body of sentient beings, and the body of sentient beings is the body of a buddha. They are different while the same, and the same while different. Thus the three are equal and unobstructed.

彼身卽是此身。此身卽是彼身。佛身卽是衆生身。衆生身卽是佛身。不同而同不異而異。故三等無礙。

The root is the same; the form is different. It is so for you and that person too. You are in the same light, never separate at the root, and still you are you and they are they. You do not melt into one.
Shingon Buddhism later came to call this being “two, yet not two” — nini funi. The root is the same; the form is different. It is that one line, nothing more. You need not remember the name. What is worth remembering is only this: that person has not gone far away.
So “Welcome home” is not an account of the route a soul has travelled. Nor is it merely talking to a memory. You are calling out to someone from whom you were never separated in the first place. That is all it is. Call, and it reaches them. That is the answer about Obon.
