The Yagya happens in Vrindavan. The person it is performed for is usually somewhere else, often eight thousand miles else. That is the first honest question anybody should ask about this work, and it deserves a straight answer rather than a shrug.
What the tradition puts first
The Taittiriya Upanishad gives an order of creation, and the order is worth reading slowly.
Space arrives second. The Self is first, and space comes out of it, followed by air, fire, water and earth. In that account distance is not the floor everything else stands on. Distance is one of the things that came later.
Modern habit runs the other way round. We take space and time as the given, and treat mind as something that happens inside them, in a skull, at a location. If that is the true order, then a Yagya in Vrindavan and a man in Los Angeles have a real problem: eight thousand miles of it. If the older order is the true one, the problem was never there.
Thought has its own rules
Every made thing began as a thought. Somebody wanted to reach what was above them, and afterwards there was a ladder. The wanting came first and the wood came second, and that order never reverses. A plant turns toward the sun before it has grown the leaf that will catch it.
Thought is not subject to the rules that matter obeys. It has no weight and takes up no room, it is not slowed by the distance between two people, and two people at opposite ends of a country can arrive at the same thought on the same afternoon without anything passing between them that a physicist could weigh. Most people have had that happen and have not thought much about it.
We are not going to dress this up in physics. It is tempting to reach for particles and entanglement and it is a mistake, because borrowing physics concedes the very thing the tradition denies: that a thought needs a physical carrier before it can be taken seriously.
What that means for a name in a Yagya
At the opening of every Yagya the Brahmin makes the Sankalpa, the declaration of conscious resolution: the day, the place, the purpose, and the names of the people the rite is performed for. What the Yagya sends is not a substance that has to cross the distance. It is an intention, spoken aloud and fixed on a named person, and an intention is not measured in miles.
This is why the tradition treats the naming as the essential act rather than the attendance. The offerings, the fire, the water in the pots, all of that happens in one room in one town. The person named does not have to be in the room, because the part of the rite that concerns them is not made of anything that would need to travel.
What we do not claim
We are not telling you what will happen in your life. We tell you exactly what is performed, on which date, by whom, and we send you the recording so that every part of that is checkable. What the tradition holds about distance is stated above as what the tradition holds. Whether you accept it is properly yours to decide, and you can watch the fire either way.
