In DN 16 it is written that:
"Then the Buddha came to the Ganges River.
Now at that time the Ganges was full to the brim so a crow could drink from it. Wanting to cross from the near to the far shore, some people were seeking a boat, some a dinghy, while some were tying up a raft. But, as easily as a strong person would extend or contract their arm, the Buddha, together with the mendicant Saṅgha, vanished from the near shore and landed on the far shore.
He saw all those people wanting to cross over. Knowing the meaning of this, on that occasion the Buddha was inspired to exclaim:
'Those who cross a river or stream have built a bridge and left the marshes behind. While some people are still tying a raft, intelligent people have crossed over.'"
My only question is how did such teleportation happen? Is it metaphorical?
What are your thoughts on it?
